I am a "republican", small "r" as you would say. I pay yearly fee to a "republican association" in a country that is a monarchy, the goal is to end the monarchy. Nothing of it has to do with the US or its Republican party. Get a grip, learn history. Other countries also have shitty political parties using that ethymology ("Les Républicains" in France for instance). Let that ideology burn, and let republicanism [1] thrive.

[1] Republicanism is a political ideology that encompasses a range of ideas from civic virtue, political participation, harms of corruption, positives of mixed constitution, rule of law, and others.
