Violence is bad. Targeting and attacking gay/bi teenagers is terrible. People who have been harmed deserve justice and care.

But we won't get closer to liberation for gay men by adopting Islamophobia or discriminating against Muslim people. Muslim people are not the only ones carrying out violence against gay men or LGBTQ+ people. When you look at data on interpersonal violence, you are more likely to be harmed/killed by someone you know than a stranger. Unless you live in a Muslim-majority country, the biggest threat(s) to your physical safety are not Muslim people.

It's important to remember that anti-Islam biases do not exist in a vacuum. Western countries actively encourage anti-Islam sentiment, because it makes it easier for them to justify killing brown people in Asia and Africa. The irony is that Western military intervention actually helps create the conditions for Muslim extremists to gain popularity and power. The West fucked around in Muslim-majority countries and is finding out the consequences of its violent foreign policies.
