Israel made a mistake in handing a PR coup to the anti-semites. They should have been allowed to visit and expose themselves for the bigots that they are.
Agreed. But it is worth noting that all they did was decline to offer an exemption to a law that has blocked hundreds of BDS activists from entering. Claiming that they're doing something new to target Omar and Tlaib based on their color, as many people are doing, is blatantly false.
The likes of James Trafficant never wanted to visit Israel, so there's no real point to compare.
