Did he have a wrong political opinion on some minor item decades ago or something?

He told his viewers to have someone record them while they snuck up behind women & touched their stomachs then upload the videos.

And when a woman in the audience at one of his stand-up gigs got up to leave, he demanded to know why and she said she didn't think his joke about rape was funny, he asked the audience, "Wouldn't it be funny if someone raped her right now?"

That rape joke was pretty lousy, and he had to apologise for it. Seems like an overreaction to cancel him, but whatever. You do you.

Did you miss the part where he encouraged men to walk up behind women and inappropriately touch them without consent?

Not only that, he wanted them to record the acts and put them out on the Internet, also presumably without the victims' permission.
