Although this isn't even a matter of opinion, it's statistically proven that guns are bad for the population, and that the complete lack of control of them is complete bonkers. The US is full of ignorant people so we understand why things are the way they are, but don't come here calling it culture. "gun culture", that's like claiming that female genital mutilation in Nigeria is "culture"
this is the problem i'm afraid, the idea these kids deserve an unopposed run at pushing an agenda just because there school was shot up. 'victims' rarely offer a balanced opinion, which is understandable. humans are shaped by experience.
Europe's relationship with guns is entirely different from America. In covered wagon times, in an infant country, in a lawless frontier, the gun was a protector from invaders, wild animals. Europe was already a well established continent long before practical firearms existed. You can see why guns would have had a greater role in American history than Europe's, and therefore a greater significance traditionally.
guns bad for the population? so are sugary drinks, fatty foods, alcohol, cigarettes and automobiles. all of these things kill more people in USA a year than guns.
over half of firearm related deaths in USA are suicides, which again reiterates the mental health issues that must be addresed. Mass shooting fatalities take up a tiny fraction of overall firearm related deaths. The overwhelming majority of those who own firearms are responsible, reasonable owners.
I don't think comparing gun culture to FGM 'culture' is relevant. FGM is a cruel practice in and of itself. Guns are a hobby that can be misused. A more reasonable comparison would be car culture, as a car is something innocuous on it's own that has potential lethality.
