It could possibly be something else yes. Michael Savage is another fairly loud public speaker who UK government won’t let visit ( and his support for Israel is not nearly as consistent as Geller’s). Still, both of these people appear to be responsible citizens lacking any threat to UK like so many of the people UK let’s visit Or, for that matter, move in. ( USA suffers from its own open borders and inconsistencies of course. As does Israel. The enemy within is regrettably alive and well in all three. ( and several more) countries these date. And pointing it out can be viewed as. “ politically incorrect “ by those in charge. Not a good omen for our future.
Savage had never visited the UK and was never going to visit here, so its ironic that he plays up his banning.
