Well, if I say ''I need a way to disable redpower's microblocks'' I am obviously talking about microblocks, someone with a bit of brain would get what I mean.
The issue here is that you are making massive assumptions about the untyped/assumed content of your post in regards to what others are going to understand as such. As you originally made no mention at all regarding anything else except removing microblocks, you had one possible way (at least as far as I know) to satisfy the request, which is removing RedPower2 entirely.
It has nothing to do with having "a bit of brain", but more to do with answering your question without making undue assumptions. Next time, please try and include all required information in your question.
Er, Guswut's reply was sarcasm, noting that that's the only way to get rid of them.
Nope, not sarcasm, actually. I was answering his question. If he had included that he wanted to keep RedPower2 enabled, I'd have replied with either "I don't believe there is a way", "ERROR - PATH INCOMPLETE", or perhaps I'd have left him to someone else to try and educate on as much.
It comes with the territory of being a computer, eh?
