The main thing, I think, is to make sure you're in the fandom for your own sake, that being a furry to you is what it means to you and no one else. Everybody has different views on everything, some people want to go very over the top with their character, that's there choice and I fully support that, even if it might not necessarily be for me. But the fandom is a single entity, you join and be apart of the fandom for what the fandom means to you, there may be some people in it who disagree, but they don't matter, you're in it because you like fursuiting, you like the furry art, and that's all that's really important.
There are many good people to show your friends, but if they don't need convincing then no need to show them, only if they challenge you on it. But basically the idea is don't worry about what other people do who are in the same fandom, focus on what the fandom means to you and stick to that when figuring out whether you want to be apart of it or not.
