Should I Have Opted for A Polite 'No Thanks'?

Another OKC adventure.

A guy starts messaging me.  He looks nice from his one pic; his profile is a little empty.  His first message is brief, but I decide to give it a chance.  We're talking; it turns out we're in the same line of work.

We start having a nice conversation about that; I then ask him where he likes to hang out.  He starts talking about his neighborhood.  He made the comment that he's had some trouble meeting women in his neighborhood.  Why so, I ask?

"They are all fake and lame."

Well, something about this didn't really sit right with me, and I kind of felt like I was at a crossroads in the conversation with him anyway.  I wasn't really sure if we were hitting it off and had much in common besides the same line of work.  I didn't reply.

I received another message (which I found odd, seeing I hadn't replied yet).

"Would you like to go out sometime?"

I suppose I could have written back a polite 'no thanks'.  I'm bad about that with online dating.

Then another message:

"Happy Easter."

"I know you're busy and all, but I find it hard to believe it could take you that long to type a couple words."

"You can't answer a simple question?"

At this point, I have blocked him.  And I feel confident I have made the right decision.  I'm curious if he's tried to message me again and received some kind of notification that he's blocked.  And I fear the day I randomly run into him at an industry function.
