Because it's not saying Chinese people look like Winnie the Pooh. It's only Xi looks like Winnie the Pooh. Do you understand the distinction between insulting an ethnicity and insulting an individual?

And you must've been living under a rock (or behind a firewall in an authoritarian country) if you've never heard of Xi being compared to Winnie the Pooh. I hear he's sensitive about it, and it's banned to make such statements in China. But since I'm not in China and Xi is a piece of shit, this incentivizes me to insult that shithead in ways that hurts his fragile little ego.

Oh bother!
