It's simple minded naive thinking such as the OP that is the problem today...
People love power and control, this trumps almost all else...
An idea such as globalism sounds to the average moron (such as yourself) like a great idea and what bad could come from such an idea..

The reality is that when you break down barriers that have always been there for good reasons, such as sovereignty and currency, it just becomes a way for a select group to take more power and control in serving their own misguided interests.
The left wants to destroy western civilisation for a eutopian fantasy ( one that can never exist ) where Muslims and whites hold hands and everybody is happy and can be whatever sex or whatever freak show they want. The left only see what they want to believe, not the truth. Their foolish ideal and its failure, that is, not all people are good when given a chance, that races do actually exist, that gender is real and serves very real biological and social purpose and that it is human nature to battle and to fear people who are different from yourself, and that none of these facts will EVER change.
That's why leftists are so stupid they can't see through the first layer of naïveté.
