It is not just a question of popularity. Post 9/11 skillsets around chemical ( or other scary looking domains ) became vilified within general populace and then that vilification was normalized with shows like 24 ( which is a great show... it just sucks that people are unable to separate the world it presents from their world ). It does not help with the advent of red flag laws, where neighbors can effectively call cops on you if they see something that bothers them..
