The reason is that Wikipedia can be edited by those who are members. The liberal members are constantly monitoring and changing back any conservative edits. Apparently conservatives don’t care enough to do the same. Or maybe they are just busy making a living.
“Or maybe they are just busy making a living.”
I think that’s it!
Liberals seem to always have their protests, marches, meetings during a week day. Conservatives don’t typically have those things because they are working and keep weekends for family time and church. When we have Tea Party rallies, they were always in evenings or weekends.
I imagine conservatives aren’t spending all their time trying to convince others of our side. It’s probably to our detriment, but is part of being comfortable that we are right and letting others live their own lives. NOT something liberals ever do.
