What if it's because I oppose the muslim ban and refuse to enter the US? That's a serious question. Actually I feel like the response to that will be, "It's your choice" but hey solidarity man!
Edit: Words are hard!
Edit2: Yes, downvote me & upvote the hyperbole. Welcome to the post-fact world. All Muslims are banned. Trump is Hitler. The stock market's going to crash. Anyone right of Obama is racist scum who should lose their job. Etc.
It's probably an attempt to show the delta between Obama & Trump isn't as large as some imagine.
According to you we should wait for things to reach peak bigotry before reacting. Would you have the same "oh no big deal" reaction if a single Christian country was banned mainly for being christian?
If anything, a falsehood weakens the position of the person making the argument. It's easier to defend the truth. It's more robust.
