Republicans are currently the ones undermining the foundations or our republic, stripping rights from minorites (Texas just passed a bill that made it illegal to be trans), deporting people with no due process, arresting dissenting politicians and academics.
They're the ones plunging this country into economical ruin, destroying medicare and medicaid to transfer the savings to the 1% through massive tax cuts while letting everyone that depended on these programs die.
Everyone in support of these ideas is intolerant in my book, and I don't see why I should show empathy to a people that would rather see me in a camp.
