Yes, precisely. It’s reductio ad absurdum. Trannies claim they’re “real women” so if the only reason a straight lad won’t ride some 6’2 she male built like a brick shithouse is because they’re trannies this is claimed to be a form of bigotry. So you take that reasoning to its extreme on the other side of the argument, and insist that anyone who thinks you should fuck the brick shithouse lest you be a bigot is not respecting your sexual identity and thus they are the bigot. It’s using their own logic against them to demonstrate the absurdity of their logic, just as Aristotle taught us to do.
