Silver,
A slippery slope argument, or a claim that I was holding such things to be equal, could not be derived from my post by a reading in good faith. Nonetheless, I'll blank it, since you find it offensive enough to make such a claim about my argument.
To put it more concretely, when someone makes the argument of "we don't treat types W, X, and Z (some of which are possibly worse, and some possibly 'better' than type Y) in such a way, so why should we treat type Y differently?", the appropriate response is not to come back with "you must think type Y isn't very bad!".
That's both a personal attack, and a bullshit move.
