"I know I'm going to get downvoted by X mains"

If you put that in your post, you lose all credibility in my eyes. Putting that in attacks the opposition, instead of trying to prove your point. You attack people who actually disagree with you, who aren't mains, by labeling them as something negative, and you're attacking those mains who are willing to have a discussion. You're saying that your argument is pretty much infallible, and the only reasons you're being downvoted is some asshole main who is too biased to see the truth.

Secondly, it makes your post of a possible discussion, into an attack on the opposing side. You label people's opinions and arguments obsolete by calling them a witch, and then trying to set them on fire. Not only are you killing discussion, you're also generalizing an entire group as insensible people, which isn't true.

It's like you're arguing that Left Twix is better than Right Twix, but instead of listing that Left Twix is better because it cascades it's caramel and bathes in chocolate, you're saying that Left Twix is better because Right Twix is too biased to agree with you. In actuality, you yourself are being more biased than the people you're trying to attack.

So stop it. Don't ruin your argument.
