It’s just something I don’t consider as important enough to make fun or condescend another towards. It’s not like there is an eternal scientific hell for non-globe believers. Or maybe there is, who knows.
"Condescend" is actually an intransitive verb, so
you would have to say something like "be
condescending toward".
Like other social tools, grammar Nazi, teasing,
condescending, making fun, etc can be used as
a force for good or ill.
They are all useful for kind of keeping eachother
on an even keel.
They can also be used for bullying etc.
In this case, if a person privately believes
the silliest things, let them. IF though,they
try to influence others to adopt some idiocy,
then they may well call in the cavalry to
bring them back in line.
