Pointing out that commenters, including yourself, have simply engaged in ad hominem attacks is not a tu quoque.
Why isn’t it a tuo quoque? Because you don’t seem to have a point other than your ad hominem for me to discredit, and I’m complaining that the only substance of your attack is an ad hominem. I’m not trying to deflect from any greater point that you have: you don’t have one (or at least you don’t have one that you’ve logically supported). And to the extent that legitimate arguments have been raised by others, I think I’ve done my best to address them in a factually-supported, logical manner.
It would be pretty ridiculous if it was always a tuo quoque to point out that someone is engaging in ad hominems. On the other hand, your response could be a tuo quoque since you seem to be using it to deflect my criticism of your ad hominems.
