There is a lot of "What you want to do is stupid. The way it has to be done is...."
Sometimes, some guidance (sans condescension) is needed (where the question just doesn't make sense, like switching a 220 volt 2kw load with a 2N2222 transistor), but many people are asking for help with a specific, realistic, way of doing things. In this case, it's a thought-out, valid approach. He shouldn't have to justify his reasons for wanting to do it that way, nor be ridiculed for his approach.
This may be why this forum is a collection of old farts and many posters never return after asking one question.
Suggesting alternatives is great. Saying that your approach is the absolute, must be done this way, only correct way to do it and any other approach is stupid is less than helpful.
