Oh, do you mean this FBI website?

Many street gang members join the military to escape the gang lifestyle or as an alternative to incarceration, but often revert back to their gang associations once they encounter other gang members in the military. Other gangs target the US military and defense systems to expand their territory, facilitate criminal activity such as weapons and drug trafficking, or to receive weapons and combat training that they may transfer back to their gang. Incidents of weapons theft and trafficking may have a negative impact on public safety or pose a threat to law enforcement officials.

Gang recruitment of active duty military personnel constitutes a significant criminal threat to the US military. Members of nearly every major street gang, as well as some prison gangs and OMGs, have been reported on both domestic and international military installations, according to NGIC analysis and multiple law enforcement reporting. Through transfers and deployments, military-affiliated gang members expand their culture and operations to new regions nationwide and worldwide, undermining security and law enforcement efforts to combat crime. Gang members with military training pose a unique threat to law enforcement personnel because of their distinctive weapons and combat training skills and their ability to transfer these skills to fellow gang members.
If I say that some number of Marines are gang affiliated, which is 100% fact, you twist that into attacking every Marine? 40,000 comes from the entirety of the military, which is upwards of 2,000,000. So, yes 2% of that is 40,000. So, today we have 16 Marines arrested for smuggling people and running drugs, traditional gang activities, and you want to act like it's impossible that game infiltration could possibly be happening there?
So again, when faced with a position that you can't or don't want to defend, you toss out this straw man argument. Instead of just conceding that gang activity is widespread in each branch of the military and a threat, you start posting pictures of people maimed in combat and saying that I am calling them all gang member. That's a complete misrepresentation of anything that I have said.
You don't seem to operate under anything other than absolutism. If there is a group of Democrats who espouse socialism, then all Democrats are socialists. If someone points out that gangs are represented in the military at a higher proportion than they are the civilian world, they are saying that every member of the military is a gang member. I'm sure that's what you will be responding to this post with as well.
