Just like anything there are those that are real and those that aren't. The few that are not walking the path but pretend to do so make us all look bad. If we are all judged of the worst of our peers, no matter the group, then there is no good anywhere.One more thought.
I know a lot of shitty people, many divorced, that bang their bible and they think it cures them. It doesn't.
"First remove the beam out of your own eye, and then you can see clearly to remove the speck out of your*brother's eye."
Even those in the group that are pretending I try not to judge to harshly without speaking to them first. All are sinners...
