Still doesn't sound like they're friends, just friendly aquaintances or even just "someone I hang out with," which is not the same catagory of person as is a friend.

I'll add this, as well, though. We tailor our conversations all the time to be considerate of others. You don't tell jokes about the company in front of the owner, for example. You don't scream "fire" in the theatre, even if it would be funny.

If you can hold those forms of jokes to a minimum around those friends, you aren't hurting anything. They DO have the right to tell you their boundaries and ask you not to cross them in an aggressive manner. Granted, you have the right to cross them anyhow, but the consequence may be that they begin to avoid you, and the friends you do want to see drift away with them, because through continuing it, you have forced them to choose... this friend or that one?

Also, remember this. You are the sum total of everything that you are. Because someone is offended by sexual innuendo, for example, doesn't mean they don't very clearly see your generous and friendly nature. Or your sincerity, or worthiness to be trusted. The many, varied, and endless variety of other things which make you who you are instead of someone else. Does what color you like your socks matter? Would you be heartbroken and feel rejected if the boss said, "from now on, wear blue socks."? It is a small part of your personality that you like brown socks. One small aspect of the wondrous and varied being you are. Even if you wear brown socks, you're still the same joking, easy-going, caring person. That's not changed simply because one aspect of your personality causes and abrasive friction with someone else. You retain the hopes, the dreams, the fears, the personality that you have, even if some small part of it is "no thanks" to some common aquaintances. They are not asking you to become someone else, to lose your personality. They are giving you fair, honest, and sincere warning, "If this continues, it will push me away" and face it... the others may follow.

It's a healthy boundary they are trying to establish with you. They are trying to help you to get along with them better. They are explaining how something you do feels like an aggressive attack on them and causes them great discomfort.

You can certainly choose to ignore this. You can certainly say that they are being babies and thinking everything is about them. You have the right to tell them to "suck it up" or even to "go to hell." Is it worth it? Which is easier, let that one small, insignificant part of your whole hide while they are around, or stand on "principle" of what your "rights" are, and possibly lose an entire circle of friends over it?

Keep in mind, though, when the "catagory" is not clear, then you can only do so much, and if you give it fair effort, then it becomes they who are being unreasonable, and this, your friends will see, as well, if they are intelligent and worth keeping.
