Yes, see, if you sell guns, but you only sell guns to people who promise to use them for defense, but don't sell them to people who promise to murder, that makes you an activist gun seller and personally responsible for whatever happens with those guns.
That simile captures perfectly the logic here. I don't think it's technically sarcasm
EDIT: a better simile would be if guns were giving away for free. You can see how that could be construed as increasing the responsibility of the provider if a receiver then does something illegal with it

Either you wanted to be sarcastic or your simile did not work well.
