43% of what?

That's a really small sample group - 1,003 people. The article link goes on to qualify only "363 Republicans". So we're saying maybe 156 people think that.

Numbers are from the link in the article that I copy and pasted below:

"These are findings from an Ipsos poll conducted August 3-6, 2018. For the survey, a sample of roughly 1,003 adults age 18+ from the continental U.S., Alaska and Hawaii was interviewed online in English. The sample includes 323 Democrats, 363 Republicans, and 207 Independents"

If society devolves into a tit-for-tat game of disenfranchising the "other team" we're in for a lot of trouble. And yes that includes shutting down your opponents on "private" platforms.
