This doesn’t happen just on Lemmy. This happens on all social media. Everyone has their own little bubbles these days, and you must be 100% dedicated to the cause. Even the mere suggestion that the other side may have a point on anything is considered weakness and will get you labelled as a traitor to the cause. This is not only the state of politics these days, but the state of any topic of controversy: Sex, politics, religion, women’s rights, LGBT rights, anything. You either must be 100% for or 100% against. Try to find a middle ground and you’re just likely to find yourself ostracized by both sides.
