That's why there's no point in arguing with people holding a strong bias and aren't willing to admit they don't know everything and seek truth.

Some people decide they know it all and go on the internet to debate and throw their thoughts out, and even if information comes back at them proving them wrong they pay it no attention, they aren't interested in wisdom or knowledge because it takes humility in order to attain it.

Sometimes people do the right thing, other times the wrong thing, often it's something in between. Most people decide all one group does is evil or good and can't think coherently.
