I'm lucky enough not to have any WT relatives, unless you count my in-laws. No one's DFed me (yet) so that's not an issue. Sometimes, I actually think it would be a plus. I've thought about DAing myself more than once over the years. Ultimately, DFing is about power and reinforcing the Borg mentality. If they succeed in pressuring you back in, then that's an admission that they were right and you were wrong. And since they think it's "tough love" on their part, they see themselves as making all the sacrifices on your behalf. This makes it a lot easier.
How twisted is that?
I'm also not a strongly family oriented person, so this next part is easy for me to say. But anyone who shunned me would either be shunned in return, or find me constantly walking up to them just to say, "Hi! How ya doin'?" Big happy smile, hand out, or arms spread wide for a hug. You know the drill.
One of the things about shunning is that it makes them feel superior as they are sitting in judgment of you. I'd prefer not to let it get to me.
