Don't know how to feel about this

So I've been talking to this guy for a while and things have been going well. My only issues is that he loves to joke around and we have a lot of immature conversations rather than convos about anything serious or about things that are actually important in our lives. Not being over critical or anything, just something I noticed. Generally, I liked talking to him and getting to know him, we were on a good road.

I work at a psychiatric ward and I care a lot about the people I work with. Some have severe pathologies like schizophrenia, bipolar, mania, and some with autism. I'm really passionate about mental health and working against all the stigma around it such as labeling people with mental illness as crazy or something else.

So this is what he messaged me. It felt kind of unnecessary in my opinion. I haven't talked to him after this, it's been a couple of days. Im not jumping to any conclusions just wanted to know what you guys thought about this.
