Yes, but you're not trying to focus on them. You're just looking for a quick, one-size-fits-all approach, and hang the collateral damage because you don't want to expend the effort to think more specifically.
Let me put it this way. When I was 19, I was assaulted on the street by a man who, after he was arrested and further investigated, turned out to have killed at least two other people. I was fortunate enough to get away, and after that, I became a big fan of the right to own firearms. I wasn't taking SSRIs only because they hadn't been invented yet. I started taking them right after they came out. I have never had even the slightest sign of being violent or dangerous in any way, but according to you, I should have been denied my Constitutional right to protect myself. Not because of any indication that I was a danger, but because someone else might be a danger and happened to be the same age and be taking the same medication.
Yeah, I'm thinking you need to suck up your lazy thinking and drill down a little deeper. The age isn't the problem; the SSRIs aren't the problem. Think hard, and see if you can identify the actual problem, instead of just looking for a quick fix.
