Worse yet, they are proud of themselves.

As a Catholic (if lapsed and partly because of what you've said) I can whole heartedly state I do not recognise what some segments of my denomination have been twisted into.

That's the problem with using faith as a shield instead of a guide. People picking and choosing which parts benefit them in the moment.

Opportunistic people will use whatever they can and religion by nature contains morality and behaviour so it's easy to use that as a tool

I agree. Anyone that can justify such actions but not apply the same template to others is a biased twerp.

Those people use religion as a mask for their own insecurities and failures, yet they use it as a basis to judge others.

Don’t get be started on all these “ it’s a part of the plan” enablers. Can we for a moment keep our beliefs aside and talk like freakin humans without bring up that someone who apparently watches people during private hours!
