If Christians are to be tolerant and seeking truth, how come this sub gets vicious when someone questions the trinity and disembodied souls in heaven?

I noticed there are two pervasive beliefs on this sub that can't be questioned without hell breaking loose.

1. The doctrine of the trinity

2. Disembodied souls going to heaven as soon as someone dies

There are major major problems with these beliefs if we're going by what Scripture tells us, both of them are false teachings

But what causes this sub to become uncivilized and viciously attack anyone who questions these 2 points?
