So... national socialists and National Christians have a lot of overlap in the Venn diagram... to deny or miss those parallels seems disingenuous or ill informed.
I'm not informed of the British political landscape, so I can't speak to that.
And no, not every Christian is a NACHRIST, and it also isn't a coincidence that NAZI's co-oped and used Christianity opportunistically when it suited them.
And it's near universal because fascism is the major exception as it really doesn't desire any conformity from the designated inferior. That's what distinguishes the policies of NSDAP from prior cases of anti-Jewish oppression - the Nazi party wasn't interested in conversions at all.
As such, you really shouldn't call anyone ill informed on political topics.
