On internet forums like this one, there is an insidious psychology that takes hold. One or two negative voices can easily feel like "the whole forum" is ganging up against you. In most cases, the loudest voices represent the views of a very, very small minority. We must also consider that the written word often loses the tone that the author intended. In person, you may be able to make some comments where you communicate a wry sarcasm through your tone of voice or facial expressions, but online that may come across in a very different way than you intended. Sarcasm is very dangerous in written forums.
This particular forum relies more than most on the anonymity of its users. That anonymity gives us great freedom to discuss things we wouldn't talk about with even our closest friends in real life. But, it also gives an opportunity for "trolls" to misbehave without any repercussions. If you feel attacked, or you're feeling empathy for someone else being attacked here, consider that the opinions of anonymous internet trolls should have absolutely no impact on you. Let it go, don't escalate it.
