> I wonder if the real problem here is that people who are conservatively minded are just naturally less comfortable with social conflict. I know my progressive friends are in all regards much more opinionated and seem far more comfortable with conflict, where as my conservative friends tend to be the types of people who avoid conflict.

Exactly, conservatives do not want change, and therefore do not want a conflict associated with the change. However, liberals and progressives push for changes because they simply do not value "do the things as in the past" nearly as much as their respective values, and every change means, potentially, a conflict.
