What fallacy is this?

In response to a rebuttal on calling Gender Dysphoria a 'fetish':

Mr. Wasserberg, the second article was written by a trans person. This is a clear conflict of interest, making it an unreliable source....The last bit of the quote is important, as it indicates that the article has little to do with anything else other than feminist thought.

The argument presented in the given passage contains a logical fallacy known as **ad hominem**.

An **ad hominem** fallacy occurs when someone attacks the character, motive, or other attribute of the person making an argument rather than addressing the substance of the argument itself. Instead of engaging with the actual points or evidence presented in the rebuttal, the response dismisses the article simply because it was written by a trans person, implying that this automatically constitutes a "conflict of interest" and renders the source unreliable. This dismissal does not engage with the argument or the evidence presented in the article and instead attacks the author's identity or perceived bias.

Furthermore, the claim that the article is primarily about feminist thought and therefore should be dismissed also hints at a potential **genetic fallacy**. The genetic fallacy occurs when a claim is rejected based on its origin instead of its merit. The source or background (i.e., feminist thought) being used to discredit the argument fails to engage with the actual content of the article.

Addressing logical fallacies is crucial for a productive and fair discussion, as they divert from engaging with the actual arguments and evidence that should be the focus of any reasoned debate.
