Because Christians (mostly Protestants) have labeled anyone who questions or disagrees with Israel on any issue a "Nazi" or "antisemitic", there is a growing movement of people on the right (many of which are younger as well) being more vocal about their feelings on this topic. The fact Charlie Kirk, a moderate, was questioning Israel should be enough evidence that merely questioning or disagreeing isn't the same thing as "hating" Jews.
The younger generations (like Gen Z) aren't scared of being called "antisemitic", "Nazis", or "racist". They don't give it any power and instead just embrace it to expose them for not having an argument but only reacting on feelings and resorting to ad hominem attacks. These [mostly protestant] Christians who put Israel above America have created an environment where people like Nick Fuentes is building momentum when he was essentially blacklisted for years prior. Do you want more people on the right to follow him? If so, then keep doing what you're doing by calling them "antisemitic", "racist", or "Nazis" instead of engaging in substantive debate over their contentions.
