We've always had disagreements over policy. Those are nothing new.
What's different is that people now see all of these as existentially important, so they won't accept being on the losing end like normal people who get outvoted in a democracy. That's why people storm the capital building in response to losing a close election and try to assassinate supreme court justices because they don't like a particular ruling. Those are really extreme examples of course, but they follow logically from other violations of ordinary democratic norms, like refusing to vote on a president's supreme court nominee or trying to impose a vaccine mandate by EO that you openly acknowledge is probably unconstitutional.
Basically, if your response to being on the losing end of abortion, gay rights, gun control, or whatever is that this must not stand and we must take the streets, you're part of the problem.
