My far RW, "disabled" Vet, racist neighbor just did me an incredible favor--not sure how to

[enlightenment]

9. I'm glad you got some needed assistance

perhaps in exchange, you could stop thinking about him with a few of the terms you tossed out in your post.

If he is a veteran, then he is not "living off the teat" anymore than any other veteran. He earned the pension he receives.
If he is on disability, then assume it is earned not just something he fakes because he is overweight - as you said, not all problems are evident.
If he spends his money on new vehicles, that's his business, isn't it?

I guess what I'm saying is that it appears that because you dislike his politics, you dislike what you see about him.

If you liked his politics, would you feel differently about those things? If he were a solid liberal would he still be "living off the teat" or possibly faking a disability because he's obese or spending his money unwisely because he buys big trucks and slaps liberal bumper stickers on the back?

It sounds like you have tried to look past the politics to the person; I'd say that's a good thing. Maybe if you put the person before his political views you might find it easier to continue being a good neighbor.

I apologize if you have already thought this through; I'm just observing what I see in your post.
