Is this a tatulogy?

From here:

And you did not retract your statement, where you defined masturbation, which is the act of discharging semen not in the act of sexual reproduction to include discharging semen in the act of sexual reproduction. This is like saying black is white or night is day. It is inexcusable. Before leaping up to make additional false accusations and saying additional arrant logical fallacies, please acknowledge your defeat on this point before moving on to the next.

 

The next point will be just as disappointing to you, however: the act of sexual reproduction is the act of sexual reproduction, otherwise known as coitus, whether or not the act culminates in reproducing the young. So, after saying black is white, you say white is not white.

 

The reason why sex should and must be defined as the reproductive act is that anything else is illogical, insane, and, frankly, unhealthy. Humans have allowed new venereal diseases to spread in the modern generation which were unknown in the ancient world, since the pursuit of perverse sexual pleasure, involving the abuse of sexual organs by thrusting them into orifices where nature never intended them to do, is unhealthy, and spreads disease.

 

To me, sex is sex and perversion is perversion. That is because a thing is what it is. I am not ignoring what you call other applications: to the contrary what I am doing is correctly identifying them as sexual perversions, that is, namely, an unnatural abuse or misuse of the sexual organs by those to whom the natural pleasures of the natural uses thereof are insufficiently stimulating.

 

To me, the sex act is the sexual reproductive act. Masturbation is not the sex act, it is self gratification by an abuse of those organs.

 

You see the problem you are having is that facts and logic are on my side. All you have is a dark, turgid, hysterical emotion based on a frantic denial of reality and a love of wrongdoing. I am not from the generation where everyone is given a participation trophy. You speak in ignorance. Your thoughts are not in order. You misuse common philosophical terms. Your behavior is a simple and neurotic trick of merely accusing me of your own shortcomings, and when that accusation is proved false, merely making the next, and the next, without once actually thinking about what you are saying.

The passage you've provided contains several instances of poor reasoning, logical fallacies, and cognitive biases. Let's break them down:

1. **Strawman Fallacy**: The author misrepresents their opponent's position by claiming they define masturbation in a nonsensical way, equating it with sexual reproduction. This is likely an oversimplification or misrepresentation of the opponent's argument to make it easier to attack.

2. **False Analogy**: The author compares the misuse of sexual organs to other things that are logically unrelated, calling non-reproductive sexual acts perversions without providing a rational basis for why this classification is appropriate. This analogy fails to adequately establish why the author's definitions are the correct ones.

3. **Begging the Question**: The author assumes the conclusion within their premises. They claim that non-reproductive sexual acts are perversions without demonstrating why reproduction should be the only defining feature of sexual acts. This circular reasoning doesn't provide an independent justification for the claims made.

4. **Appeal to Nature**: The author argues that non-reproductive sexual activities are unnatural, hence wrong. This is an appeal to nature fallacy, where the assumption is that anything natural is good and anything unnatural is bad, without explaining why 'natural' is inherently better.

5. **Ad Hominem**: The author attacks the opponent’s character rather than addressing the core argument. They describe their opponent’s mentality as “hysterical emotion” and “frantic denial of reality,” which distracts from a substantive discussion of the underlying issues.

6. **Hasty Generalization**: The author concludes that the spread of new venereal diseases is due to “perverse sexual pleasure” without considering or discussing other factors that may contribute to the spread of diseases, such as lack of education, awareness, or access to healthcare.

7. **Moralistic Fallacy**: The assumption that what is considered 'morally right' (in the author's perspective) must be a fact of the world without objective evidence to support that moral position.

8. **No True Scotsman**: The author implies that those who disagree are not logical or informed, redefining the argument to exclude contrary positions without addressing the actual argument.

By employing these fallacies, the author undermines their own argument by failing to substantiate claims with reasoned logic and evidence. Instead, their argument relies heavily on rhetorical techniques and assumptions that aren't critically examined.
