The threat of swaggering or pushing changes to ImgFlip isn’t the reason we’re upset, nor even his wild and crazy views on free speech/hate speech, necessarily.
No, it’s because he walks around promoting the bigoted trash that LGBTQ people aren’t really valid and must be suffering from some mental illness.
That invalidates a healthy chunk of ImgFlip and makes him unable to serve even in a symbolic role. It’s a matter of basic human rights and recognition, not mere disagreement.
Even at the end of tough campaigns, memers can typically come together and support the winner.
But if it’s TobyThePug: doubtful. He doesn’t accept them, so why would they accept him.
His inability to serve effectively in this respect were he to win is the main reason he should just be DQ’d from the get-go. But there are plenty of other reasons why it’s a good idea for the integrity of the stream, see discussions here and elsewhere.
