Proportional representation sucks (see Israel for an example of how that can go wrong) and it will never happen because nobody can promote it without also indicating they like it because it will give their preferred political party an advantage. So it all sounds like "I want to change the democratic system so that my party will win" which puts you on the same level as people that want to rig elections.

Ranked choice voting would be a better thing to promote for people that find it difficult to accept democracy is about making compromises. In the end you'll never have a system where millions of people will get exactly what they want, but if the goal is to give immature people warm and fuzzy vibes when they vote for a party that doesn't have chance of winning, then ranked choice is a way to do that without giving political parties even more power than they already have.
