Why Is MAGA so Big And So Much Hate?

Why is MAGO so big and just full of Hate groups/ I knew there was always hate groups in USA like KKK and anything else. But is this all true. That it is this big over 60 million or more all are in a hate group? and oppose everything and want to ruin the world more or less on purpose?

Such as all voting against their own interests just to screw everyone else in the USA and rest of the world? i know all of this is a build up throughout many generations, but it is so big?
