I do care about my friends though, which is why I’m trying to fight against the current and get them to also opt out of Facebook which I see as a toxic cancer upon society. I miss out on socializing by not smoking cigarettes too.

If you've stated your preference to them and explained why you personally don't feel comfortable using Facebook, and they don't care, then they are the one being unfriendly.

Of course there are many ways to state that preference, ranging from "you're an idiot if you want to keep that advertising agency alive" to "I don't feel comfortable putting details of my personal life, including our friendship, on the Internet for private companies to profit". If someone truly belittled the second, then yeah, they aren't a friend.

If I have some friends who are into amateur radio, am I not really their friend if I don't get my own ham radio so they can contact me through that?

"Hi friend, whenever we eat together I don't want it to be a self-catered barbeque or picnic in a park, dinner at my place or yours, a meal at a great local restaurant or any other of a thousand and one possibilities. No, whenever we eat together it must be at a MacDonalds restaurant. Otherwise we can't be friends."

> And they think the same of you. If their preferred method of communication is Facebook message, are you really a friend if you don’t care?

It's hardly the same though, it's not like the other commenter's expressing a preference for a call or text where the other would be equally possible. It's exceedingly unlikely that someone with the capacity to have a preference for Facebook messaging is unable to call or text; the reverse isn't true.

Saying 'I would rather we texted' vs. email or whatever is not the same as 'I would rather you sign up for this service and use it to contact me'.

If they think the same of me then so be it. We are obviously not compatible then.

For information I still have the same set of core friends from elementary school so it has not stopped anyone that I actually care about from contacting me.

Edit: and yes as the a side comment here suggest I do not say this in a patronising way, I just explain why I am not on facebook and that there are other ways to contact me.

Assuming that they already use a computer and/or a cellphone, sending an email, making a call, or sending an SMS is much easier than creating and maintaining a Facebook account.

I would believe it if someone didn't want to use cellphones at all, for moral reasons, but that person wouldn't have a Facebook account anyway.

If I prefer social interactions at a bar and I allow a friendship to suffer because I don't respect a recovering alcoholics preference to avoid those places it makes me the arsehole, not them.
