I don't think that's a "far right Christianity" thing if a country want to limit Muslim from entering... that's just precaution since studies have found that majority of terrorist acts are perpetrated by Muslim (extremist groups of Muslim - majority of Muslims denounced violence).
I mean, the Obama admin did it... named countries that are a hot-bed for Muslim terrorist and implemented measures to prevent people from these countries to come to the US without extreme vetting.
Beside, I don't think this has to do with religion but some of these extremist group are making it into a religious fight... since majority of Palestine are Muslim and Israel are Judaism.
If you look into the religions in Israel, you'll realized that Christian is just a small slice of the religion pie.
Religion in Israel:
73.8 percent of the population is Jewish, 18 percent Muslim, 1.9 percent Christian, and 1.6 percent Druze - US Dept of State
Judaism and Christianity are not the same...
