Sometimes people try to convince you that you're on the same "side" as them.  But only because they want to use you.  In order to further their own agenda, they need to convince you that you have a shared goal and what is good for them is also good for you.  If you open your eyes and see Trump for what he really is, a parasitic leech, you'll realise that you won't see any benefit from them reaching their goal.  They don't have your best interests at heart.  You are just a means to an end for them.  Don't be someone else's pawn.
