real friends are people who don't abandon you when you do something they don't like. the problem is, until that happens you can't tell the difference.

These days the bar for that thing seems low. Like making a post on Facebook.

I dunno, you cam turn what you said into "real friends is an enabler of whatever I do and a doormat".

Someone leaving after x did something they dont like ... may just be former real friend with a backbone and moral values.

no, the reverse is that a real friend would confront you and help you correct what he thinks is a mistake, or at least discuss it to understand why, instead of canceling the friendship and worse stabbing you in the back.

if they can't confront someone for what they think is a mistake, then it's them who have no backbone, and potentially also the enabler, because you can't change someones behavior by walking away from them.

Or when something bad happens to you.
