I completely disagree on this point.
Fascist youth groups were encouraged to engage in nonmarital intercourse, to ignore Church teachings on divorce, etc.
For a long time in Germany youth groups were encouraged in to participate in deviant behavior.
Fascism utterly rejected traditional morality in Italy, Germany and Scandinavia.
Only in Vichy and Spain were Christian morals encouraged.
I would also point out that nationalism is different from patriotism and that nationalism - but especially ethnonationalism - is not conservative.
Nationalism is simply patriotism taken to a greater extreme.
I would also add that nationalism/patriotism everywhere but the US is by its very nature ethno-nationalism, because the nation in most countries is defined by ethnicity to a degree that US society is not.

Fascist societies were conservative insofar as they didn't tolerate feminism, homosexuality, etc. The fact that some of their leaders were secretly homosexual doesn't change this, any more than the fact that the observation that Saudi Royals live debauched lives changes the fact that Saudi Arabia has the strictest Sharia Law in the entire Middle East.
