There are some strong opinions and sometimes they are not worded in a way that makes all feel welcome. But if you play into being offended you only put yourself out there to prove the point you are offended by.

Offence is just how you feel about the way someone else feels, it's not really substantial and you won't find respect here by getting but hurt over it. Instead try to be part of the conversations you can, this space is about bringing different perspectives together so add what value you can and maybe you'll be able to help shape the development.

You will be best off picking your battles, and you can create your own groups if you feel there is a category missing that you would like to represent. Stay away from posts that get your hackles up if you can't converse in a logical way, use your insights to help the community grow instead of tearing down the parts you don't like.

If your friends are going to run from a challenge then this is probably the wrong place for them.

I'm not clear on the purpose of your post. Is it simply to point out that some people or ideas may be offensive?

If that is your point then yes, some people or ideas can be offensive.

Or is your point that because some may be offensive you're hesitant to invite friends?

If that is the case then I wonder if you understand the stated purpose of this endeavor.
