First, I've traveled to France every 2-3 years for the past two decades. The incident in question was on my second to last day in France, occurred a few blocks from the Eiffel Tower, a nice avenue of coffee shops, which, compared to past visits is now extremely run down, of course, relative comparison to previous visits of the same neighborhood.
Several hundred Arab looking men literally lined the streets, were checking their smart phones after dark, and anytime a woman approach, completely surrounded her, and she would be at their mercy. It was truly a gauntlet. I paid the cafe owner 100 euros to get me out safely, and he explained this is a new norm. BTW, he had to take me out a back way, and walk me four blocks to my hotel. He further explained that the police are too intimidated to stand up, and that most of these men in question are migrants. Considering he owned the place and had been there for years, I'll take his word at face value. Plus, I always stop by his cafe once or twice when visiting. Finally, I've traveled enough to know.
At the various gay bars and places within the gay community in France that one would normally visit, both older and younger gays were petrified of the Muslim influx because radical Imams who preach violence against gays are permitted to do so openly, and the authorities basically stand down to both the Imams and large groups that organize, which by the way is supposed to be criminalized in France.
The real divide in France is not French law targeting Muslim communities. Most laws that are cited in the papers about French secularism targeting Islamic communities are never actually enforced, and law enforcement is afraid to confront Islamic areas of France, let alone enforce not wearing hijabs in public in Islamic areas. It's like old 1800's laws in the US prohibiting purchasing milk on Sundays in rural American counties; they're on the books, but not enforced.
The real divide in the gay community over who to support is between younger and older. Both are petrified of the migration wave, because the authorities are doing nothing to preserve what they believe French secularism brought them in terms of rights, and because most of the migrants that are coming are young, unaccompanied men, and according to the gays there very militant and radicalizing French Arabs. The vast majority of the gay community does not want any more migrants, want Islam to agree to secularization or be outlawed.
The divide comes between the young and the old on politics. They younger crowd tends to like Marine's positions on Islam, and there are many who believe Marine does not go far enough. The older crowd views Islam and Marine both with suspicion, primarily because Marine's father has said some very harsh stuff about gays, as the apple cannot fall far from the tree. Honestly, if Marine did not come with her father's baggage, from all the gays that I spoke to in France, should would be the landslide choice for French gays, and still is with the younger crowd.
The real problem in all of this from those I've spoken to while there is that Muslims were small in number in France, but never really integrated. But two decades of mass migration, zero assimilation, has led to two separate groups, Muslim and French, and the recent migrations have brought a militant brand of Islam that seems, judging from their Imams, unwilling to assimilate, and a French public that has grown weary of the militant nature of Islam in a secular country. This militancy is can probably be attributed to France's lack of integrating Islam into French society by getting some level of assimilation over the decades, but it's reached the point that there are two clear groups, both of which want something different and will not respect each other.
