Where the "if" evaluates to true, YT kept guns despite them being illegal because he "wants to".
That would be putting his property in danger of confiscation, his home in danger of being raided, and his person in danger of receiving harm. For no good reason.
Now, I can see how he'd be miffed at the prospect of losing a lot of money if he handed in his weapons on an amnesty day, but that's immaterial. The fact is that LuTze's labelling of the above behaviour as "moronic" is his generic opinion of people who keep illegal weapons and has nothing to do with respecting mods on a forum.
[edit] this is like a practical example of where the law falls short of pleasing everyone
