Post all the conservative political opinions you want. As long as you stay away from posting hate, personal attacks, and similar, you're not going to lose your Twitter account
That;s a pretty standard Conservative position that I think would be well received here.
Just because it isn't a perfectly bright dividing line doesn't mean it's entirely subjective. It is also to the benefit of a side regularly spewing hate to also argue that it's subjective.
(And to be clear, none of those things short of imminent threats should ever be considered punishable by a government; that has far more negative outcomes than positive ones. But they absolutely should have consequences by individuals and groups who choose not to associate with such things.)
