While I generally agree with the sentiment that people who do not care about politics because it does not affect them are sometimes bad people. I think it's also worth noting that apathy towards politics can be born out of ignorance and not malice. To that degree, we need to inform and make people around us conscious of issues.
PS : I'm not saying that people should be forced to take on that role as it can be very draining but to some degree, it is the only way for people to change and I believe it is worthwhile to do.
PPS : I'm also not saying that this means we should invite intolerant people to change their minds or anything like that.
