If you are not out to convert people then you can hardly claim to have something that one needs to convert to, but are more leaving than coming in, contrary to the NT church.
While as for nasty posts, likening your Prot adversaries to being apes or descendants of the same, and telling people who do not love papal bulls to go back to the hellhole their ancestors came from, seems to qualify as nasty.
Now now...
It's not nasty to be nasty if one is pointing out nastiness in others.
You people show up like herpes. You take interesting threads and dirty them up and expect people to come running to your religion.
