I agree with that, especially with party politics here in the uk (can't speak for other countries but assume it's the same). As an ex-labour member and now from the outside looking in I can see that many in the parties are exhibiting cult like behaviour. Brexit is the same, it's become like a fanatical movement, a good example for me personally is a friend of mine (who I regularly have heated arguments with) doesn't care about jobs, what people have lost, the economic downturn and all the other aspects, he just want it to happen and comes up with the most ludicrous justifications for doing so. It's got to the point I actually think such people need psychiatric help!
