Donald Trump is the first presidential candidate in history who could be barred from entering Britain. Parliament is scheduled to discuss banning the GOP front-runner after close to 572,000 Brits signed a petition calling on their government to stop him from entering the country citing his bigoted comments about Muslims as a violation of hate speech laws.

While that’s actually unlikely to happen (Trump recently threatened pull more than $1 billion in investments out of Scotland if Parliament decides to go through with it), the move reflects the level of anti-Trump sentiment in Britain—as well as many other countries around the world.

Reddit users from across the globe weighed in with their perceptions of the loud-mouthed candidate, and what it might look like if he actually wins the nomination.

Most expressed shock that his candidacy was even a real thing.

“I think Britain used to see him as a prat, or a joke that went too far,” user impossiblevoyage writes. “Now we’ve realised it’s not a joke. Cue slight panic, hope that there are enough sensible Americans left to get him out of the way.”

The supportive comments in the thread were few and far between (aka nonexistent) but a few redditors tried to find positive things to say.

“He’s a megalomanic whose arrogance probably served him well as a young shark coming up in New York but now, with age, and with the terrifying prospect of a presidency, makes him seem deluded, irrational and fucking dangerous,” TropicalTortilla writes, adding, “His daughter is hot tho.”

Despite the negative feelings inspired by Trump, both in the US and abroad, there’s a good chance he could really be the nominee—or even win the election.

It’s a scary thought for most international commenters, who fear what having a large, loud fart in the White House would do to the rest of the world.
