Honestly, what you are complaining about is -I think- PD.com's best feature. Every other place on the internet I have been is so restrictive as to what you can and cannot say, and while you seem to be implying that happens here too, it really doesn't. Do people jump down your throat if they don't agree with you? Yes. And, they should. This forum is about how freedom of speech actually works, rather than how people think it should work. You say something, and people who don't like it will verbally attack you, it's your job to dance that word tango and state your case clearly, or maybe even listen to the other person and possibly learn something. Does it suck when a large handful of people jump on you all at once? Of course, it sucked when it happened to me last and will suck when it happens again, but dude, that's not a bad thing, you are being told by verbal votes that what you say is not jiving with them. They do not owe you agreement, and you do not owe THEM agreement.
This is discourse.
