Sorry you don't like America.  I do and I wouldn't live anywhere else.

I don't witness hatred, bigotry and exclusion in my day to day life.  And being 55, I remember watching racism in the south in the 60's when I grew up.  Today is nothing like that.  While today is not utopia, it gets better every day.

There are many private echo chambers out there.  Both left and right.  Your view will depend upon which one you lock yourself in.

There are threats out there.  Every month or so another country suffers a terror attack with multiple casualties.  It is a real threat, not an imaginary one
