Your post reminded me of what my 13 years old son said last week right after he got out of shower, "Dad, I used your deodorant. I hope you don't mind". Not that I could do anything if I did mind.
Now, to reply to your post. Do I mind if someone uses part of the idea from my sites and change it around to build their own site? Not really
Do I mind if someone get lazy and either copy my site or make an almost identical layout? Yes I do.
My sites are nothing special but I still don't like to see them get copied
