No, its not edgy, but the compulsion to ridicule something you don't believe is an attempt to be edgy.
I don't believe cats are superior to dogs, but I don't feel the need to pontificate on the issue. If somebody feels that way and they're not hurting anybody in the process then good for them. Now, of course there are charlatans that do hurt people, and its not just people who preach divinity; look no further than the Oval Office (and not just the last 2 years) and the religious fervor around Trump and Clinton. Religion has, if nothing else, proven to be a benefit to people. For that reason its a good thing. Go after the charlatans and the criminals, but attacking somebody's religion just because it makes you feel superior is played out.
phew
