Why do people get upset for not choosing sides?

I'm always seeing both online and in real life people saying "either you're with me or you're horrible" or "if you're not supporting me then you automatically support the other side" or something along the lines of that. A lot of people get mad especially when people don't want to be on either side and just don't want to be involved with either of them. Acting like they did some horrendous act when in reality some people just want to do their own thing without being in conflict or don't want to be in the middle of it. For me personally, there are just some things I don't want to get involved and don't want to get hated on for it.
