Oh man, this speaks to me. If I ever wake up in a bed and both my parents are in the room talking, I will know shit has well and truly hit the fan.

I think he's been keeping his head down, hasn't he been having some pretty serious legal issues?

Edit: looks like he got indicted on animal cruelty charges last year.

which might go through a wall but won't go through the neighbors wall.

This is pure fud lore. Most common shotgun self defense loads (buckshot and slugs) overpenetrate more than 5.56. A bunch of groups (including the FBI) have studied this.

Sure, birdshot won't, but birdshot also gets stopped by a heavy jacket, so that's not exactly ideal either.

An AR-15 is pretty much the ideal home defense weapon for a whole host of reasons. The light bullets not penetrating through multiple walls is one, it being WAY more reliable than most repeating or pump action shotguns is another, it's extremely easy to use effectively even for someone with very little training, etc.

Shaming someone for picking an AR as their home defense weapon is moronic, when it's one of the most often recommended choices (for very good reason.)

TL;DR, you're an ignorant asshole, who should educate themselves before lecturing others.

The bigger problem is that diseases like this are so rare, there simply isn't much money available at all for disease specific treatments. It's a tough sell to invest 100s of millions of dollars to maybe find a cure to a disease that effects single digit numbers of people in the world in any given year.
