I'm afraid it wasn't just "men" attacking that trans women, there were women also harassing her in the video, and they were all Algerians. I.e. muslims. I've seen the video; a woman grabs her by the arm and mocks her, trying to detain her from escaping before several men start grabbing/punching/surrounding the victim at once.
Just an example of the culture clash that trans people will suffer due to the demographic changes brought on by the open-door migration policies of the EU. France, Germany and Sweden have imported so many people they can no longer effectively police or integrate them, especially at such gatherings. I refuse to sugar coat the risk here - there IS one in certain European cities, particularly if you travel near muslim areas (no go zones). They do exist, despite progressives insisting for the last five years that they do not, and they more than likely are dangerous for non-passing trans people to enter. Many are already aggressive places to be for non-Muslim or non-migrant cis Europeans; being visibly trans or gay is not wise in these places.
I wouldn't count upon the various European police forces to help a trans person if attacked, either. They are largely under orders to move along anybody who might "upset" (set off) the migrants, rather than anybody who is a victim of them, and aggressive immigrants tend to band together in groups and gangs when they do this in Europe currently. Be warned. People stepped in to help this time, but they do not always do so.
We're going to see an "interesting" clash of interests between the sensibilities of muslim immigrant communities on what they see as "their" ground and the LGBT community. Already in the UK muslim areas are demanding that LGBT education be withdrawn from schools their kids attend and naturally the UK schools have capitulated to this. Some progressives might attempt to fight this but I expect it's a fool's errand given the current trend of fearing to offend muslims, and typically progressives in the west are silent when it comes to issues of islam's mistreatment of the LGBT.
Certain enclaves of Europe are not going to be very friendly to trans people in the near future. I disagree with the victim Julia's appraisal that her attackers were just "ignorant people who do not understand her situation". There's a definitely cultural/religious clash in progress, this certainly is not the first such incident and it won't be the last in which a large crowd in broad daylight tries to assault someone of the LGBT community. That typically isn't the behavior of native Europeans, even the transphobic ones. But it is typical behavior toward LGBT members by people from islamic countries, or certain countries in the African continent. The time for pussy-footing around the issue is over, trans people should be aware for their own safety of the risks to them now present in Europe.
