They are frustrated Sadistic bitches.

One of the countless things about Catholicism that has always puzzled me is that the WHOLE of the Catholic Church, aka The Universal Empire of Paedophilia and Scamming the Gullible, is 1,000% against polygamy and bigamy BUT, Nuns are called The Brides of Christ are they not?
So, is this not just Religiously endorsed POLYGAMY because the Christ can have so many Brides and we mere mortals cannot?

This is funny but that entire sister and brother bit was too much for me. Believers think it is true because we all got here by incest through Adam and Eve. This is either god's mistake or his "sin."

Tweety bird chirp chirp chirp.

I have two actual Sisters. To refer to any other women as "Sister" would feel creepy to me. I would not call the guy in the religious costume "Father" either. He ain't my Dad.

I have never spoken to a nun and I have lived in two cities, El Paso and Louisville, with a whole lot of Catholics. I am sure I would just call them Ma'am.

Her point is they should be referred to as "Sister" out of respect. Having seen how many Nuns act in Catholic School I have no respect for them, and I doubt I would acknowledge their presence at all.

I'm a none, so I don't care.

It all depends on the relationship. Sisters could fall under family or there gender in general. Religion shouldn't be brought into anything.

I call people what they want to be called as long as there's no intent to deceive. I would not call someone a Dr if i knew they were not.

Nun or sister is fine by me.

That's certainly thought provoking. For myself I'd generally respect people's titles whether or not I was part of the institution that bestowed the title. For example I would address a professor by the correct title despite me not being enrolled in any educational establishment. I'd acknowledge military titles despite never having served.

One exception does spring to mind. I would refuse to call Gillian McKeith by her preferred title "Doctor"
I don't recognise her right to the title. In fact I agree with the UK Advertising Standard Agency that using the title in connection with her unscientific nutritional advice is likely to give the misleading impression that she has medical qualifications. In fact she claims a PhD in journalism though that too is disputed.

Conversely I'd happily refer to Captain Sensible by that title if he asked me to.

It seems my instinct in this regard are less to do with whether I feel obliged to do so and more to do with whether I actively oppose either the individual or organisation declaring the title.

I'd refer to the Sisters as such simply because I'd be going along with convention, but I'm not opposed to the Catholic Church as a whole. Huge parts of it can get in the sea as far as I'm concerned but I know too many decent upstanding Catholics to tar them all with the same brush. Full disclosure: I'm related to many of those.

In the case of this story I'd read this man's actions as more less to do with him not being a Catholic, and more to do with feeling an opposition to the Church. I'm just an Atheist but I suspect the subject of this discussion (judging by this action alone) takes it a step further and is verging on Anti-Theism. I've nothing intrinsically against our more militant bretheren but it's not for me.

I would referee to a nun as a sister. I have no animosity towards them.
