>> When the Non-Jews are too religious, it is dangerous to the Jews.

these 2 statements taken together is an actual quote from R Berl Wein.
Still, this seem to be a real-life sad observation rather than an ideal. Otherwise, we would say that Chinese system of suppression of all religions is ideal, especially as it does not have many Jews.
I would suggest cautiously support proper understanding of Hashem by non-Jews, still expecting bad things possibly happening. This happened, for example, when Protestants appeared in Germany and some Jews were optimistic about it.
