Fascists ruling your nation, would be no different to your great (or great-great) grandfathers getting together to take over your modern nation and rule it. The actions they'd take virtually no different.
(ok well not your's specifically, referring to anyone without Jewish great grandparents)..
Our grandfathers valued their people being free, and being able to pursue prosperity and liberty, but didn't think foreigners should be allowed to come and take that away, nor stink up the land, or the morals of the place. And that people that acted like commies, or were godless & immoral should be sent packing.
Fascism is simply believing that your society should orientate to success and survival, and not be a doormat for others to abuse, or let itself rot.
Our great grandfathers wouldn't have wanted our people opened up to abuse and destruction for people of ill morals, or foreigners to profits and so would put his foot down on such vectors.
This is all a fascist is. A man willing to put his foot down on the vectors destroying his people and nation.
When you are willing to do that, you can be a fascist too, and finally find some honour and intelligence in your being.
