No need to apologize; I'm not a mod, so nothing drastic can be done from my end.
But I do know what that feels like, because I've been there before. In situations like that, I think people would want you to reply so that they can keep up a long discussion to invalidate pretty much everything. However, I've yet to see any such discussion that had a solid conclusion. Not saying that to speak against them, or you; essentially, I only entered to state that it wasn't worth the time. That's what I always take from those cases, and never join in with them. You are a good poster, though, so I believe you know how to handle yourself.
