just keep this in mind man
getting like that wont do anything for you
especially in politics
it makes you look like the people you're trying to refute
so it makes you look extremely stupid
if you can't come up with a way to calmly shut them down, concede. Just give up, and that's a sign of maturity. If they tease you for it, then you really won. Not measurably, but there's no greater pleasure than seeing someone act like a four year old who got to lick the spoon online because they won an argument
