@sim @katiekats This is a result of people whom validate themselves externally.  To feel good they have to seek others that share or reward them for their opinions.  The flip side of this is that people whom don't share their opinions make them uncomfortable and/or upset, so they feel a need to remove them.  This is incidentally why its not enough for these people simply to be proven wrong or false to these individuals, they have to be silenced and removed.  They cannot cope with the upset their external validation source causes them when around people with a conflicting opinion.
