Imagine youre someone that follows someone you respect. You are someone who actively supports and donates to good causes
Something happens on the otherside of the continent and you have no clue.
When your respected individual supports the cause on the otherside of the continent and begins to spread awareness, you become aware and then you do your part in donating or spreading awareness which further validates the cause
This is just one way to look at it too.. just stop with the blind hate. Do you even have good examples about why aoc is just doing this for pr?
