We could go into a whole debate about this. From my perspective, I don't think they're wrong, at the end of the day, I'm a foreigner in their country, and it's up to me to adjust my mindset. I don't think it's up to them to change their behavior because I find something offensive, that to them is not considered offensive.

You're describing a very superficial form of friendship. A true friend holds you accountable and tells you what you need to hear, even when it offends you.

> I don't generally do things that my friend would consider offensive, if they are actually my friend.

> I don't do things that I know would hurt my friends.

These two statements seem like they could be in conflict with each other. Suppose your friend has a methamphetamine addiction, but they consider it offensive for you to bring it up. Do you not bring it up ever because it's offensive to them?

No, of course not. Inaction/silence doesn't harm someone.

Furthermore, what someone who isn't me puts in their own body is none of my business.

An interesting thing I experience in making friends later in life is mapping expectations about 'what friends do' (I guess I pester and expect to be pestered about a lot of personal things, the closer the friendship the more personal the teasing should be) to expectation 'new' friends have about the relationship.
