I wasn't banned from the whole site but I definitely was perma-banned from the local subreddit. That's how reddit works. Moderators get to moderate as they see fit, and short of some egregious terms of service violations, reddit admins won't interfere.
I was also quickly banned from participating in my local sub. It is a shame that the local subs are the ones that are the most over moderated- they are effectively isolating those in the community that don't have an "acceptable" viewpoint on any given topic
