It depends. If they show any indication of preaching or proselytising, I would block. If they appear to have a respectful interest in the opinions of atheists and agnostics - just as I have a respectful interest in the opinions of religious people who are respectful and interested in my opinions - I'm more than happy to engage with them.

Are they just stalking you? Lurking? Trying to convert you? Maybe they're hoping to find confirmation for a growing atheism in themselves? That's just odd!

I would not block them. Exposure to the kinds of ideas found here is exactly what they need.

maybr they are questioning or trying to learn. I would block if the proselytized

They are always trying to proselytize. They think they will go to Heaven if they get you to believe their nonsense.

I tend to be good enough at offending them that they will leave on their own.

Do as YOUR conscience dictates.

Report them, too.

Yup. That's what the "block" button is for, LOL!

I also block trolls, men who are rude to others, make misogynistic comments, make sexual comments about women, or show sexual photos.

I even block men I notice are making these types comments to OTHER women, since I don't want to ever consider dating them.

I will talk to anyone as long as they:

Are open-minded and are willing to alter their beliefs with new evidence.

Strive to understand what is most likely to be true, not to believe what they wish to be true.

Respect the scientific method as the most reliable way of understanding the natural world.

Respect every person has the right to control of their body.

Are open to the knowledge that a god is not necessary to be a good person or to live a full and meaningful life.

Are mindful of the consequences of all their actions and recognize that they must take responsibility for them.

Treat others as they can reasonably expect themselves to be treated.

Sincerely think about my perspective.

Appreciate that we have the responsibility to consider others, including future generations.

Accept there is no one right way to live.

Agree we should leave the world a better place than they found it.

Some theists join this site with the aim of converting us. I also wonder if subconsciously they are testing their own faith.

There are a few on here today.

It depends on how they interact. If they are just lurking or asking polite questions, I will be happy to engage in conversation. It's extremely unlikely that I will be interested in pursuing any relationship with a theist. Been there, done that, and it sucked. If they get pushy or obnoxious, they get blocked, no matter what they do or don't believe.

There is no "they". Every human being is an individual, and every individual has a different story. I'll talk to anybody who is respectful. I don't require that they have my identical worldview.

Can't be very smart to believe in that stuff

It is a bit like a vegan following trophy hunting for sure

Yes I would block them too- i have blocked 2 people here for being obnoxious and was pretty sure they were bluffing being atheists.

Theys jes curious !

Seems a little bit awkward, like a drunkard going to a tea party. Just in case there is a bit of craic.

That's odd.
A guy?

What??? When someone strolls in trying to throw down some religion on us you gotta ENGAGE THEM. Thats like Evil Bart rolling into town and showing up to the saloon where wild bill deals cards. Theyre lookin to throw down! Lookin for a tussle. Engage the enemy with reason and logic and compassion.
