The problem is that "Republicanism" is spreading to other countries. Here in Canada, the Federal Conservative party now seems very like American Republicans with the attacks on various social issues such as equality (gays should be attacked), science, especially climate change, along with gas lighting and basically hateful rhetoric. Last election they scored more votes then in 40 plus years and only lost due to the collapse of the left and Trump. Their leader sounds very Trump like, except not so stupid with 50% hating him and 50% loving, or at least supporting him. In my Province, the dormant Conservative party, who hadn't won a seat in 70 years, came out of no where and also barely lost the election. Even at the municipal level, where traditionally there are no parties, they're planning on running and likely succeeding quite often.
In Europe, I see similar far right parties doing very well, perhaps not winning currently but eventually it becomes time for a change and instead of a right wing mostly interested in financial conservationism, it is social issues, immigrants etc. Hungary, now Italy to a degree, and else where, Turkey, India and in particular Israel, which seems to be doing ethnic cleansing.
