We’ll have to agree to disagree. Personally I think the key is to not use the word “bullshit” unless you’re already on good terms with someone. But you can call BS without using that word, if you’re certain your audience is easily offended.
Not caring if you offend someone? That’s also quite rude!

Yes, agree 100%. When you're busting balls with your friends it's perfectly fine, but when it's a stranger online who doesn't know you at all and is likely from a very different culture, it's not a good idea to respond that way, unless you want to offend.
