I'm 100% sure that's true for some people, but I do not believe that you can put people into two buckets: Totally against Trump and totally for Trump. I am really disinterested in people that DO fall into either of those categories, as they are beyond reason.
However, I'm interested in anyone that falls outside those categories, as those are the people whose minds can be changed.
This sounds like it would be something that's an interesting anecdote and a "GOTCHA". Has there ever been any confirmation of this from Grindr? As amusing of a story it is, it's only really useful information if it's provable.
