Just a coincidence, I'm sure.
If they're sincere in supporting Trump, I see no reason to zot them just over the born on date. This last FReepathon took over 70 days to complete and if newbies are treated as pariahs here, it will be tough for those with tenure to speed things along. I'm still considered a n00b here because of being here for a a mere five years. And one of the most active FReepers assisting with the 'thons also has a somewhat recent born on date.
It can't just be the FRe (Free Republic Elite) from the pre-2000 years keeping this site active and vibrant. Some (like me) don't have a whole lot of years ahead and some young 'uns -- so long as they're thoroughly Conservative -- can keep Free Republic at the top.
