Defend this assertion, as my credibility is not dependent on your say so. Mocking people is not in itself immature, and pointing out bad arguments is one of the central tenets of discussion.
For example, I mock sexists and racists. If you believe that makes me as bad as them or immature, then I think you have a very warped perspective on the matter. Similarly, if someone makes an illogical claim, you have an issue with me pointing it out? That seems fairly illogical itself, unless you think debate has no place on a message board.
But I don't think you believe either of those things.
I obviously meant your creditability with me and that does mean "on my say so". As for the answer-- yes, I find mocking someone with an opinion different from your own, no matter how deplorable, immature. There are ways to draw someone into a discussion without mockery. I can't fathom or tolerate racism, but if I wanted to debate or discuss a person's racist views legitimately, mocking would accomplish nothing. If I found them so repugnant that I couldn't carry a civilized conversation with them, I wouldn't waste my time on them.
Similarly, if someone is making a claim I find illogical, I would ask them why they felt that way and try to discuss it with them. If they are making an illogical claim simply to troll or bait, I would ignore them all together. Someone who is a troll cares nothing about debate or discussion and conversing with them would get no where.
Of course, you may act any way you wish. It isn't my place to police you and I am certainly not trying to. I just find it hard to take anyone seriously as soon as they start saying how "they gain satisfaction by mocking a thread". I equate it with those who post how they'd be happy if >insert fan wants< never happened so that they could revel in their tears. My opinion, naturally. I just find it immature and incendiary.
And to be fair, I think at some point everyone as mocked someone. Even myself, and when I did it, it was completely immature and I apologized right away. I am sure I do it without thinking sometimes too, that doesn't alter the fact that it lacks maturity.
