Right, so, any two things that get you from A to B are identical? Unix isn't more powerful than Windows; You can outrun a cop-car in your Prius; Apple pie is apple pie?
There's a lot more that goes into doing a job than just the physical possibility. In the context of programming there's maintainability, developer time spent and a million other factors. The blub argument, specifically the part about 'looking up', is quite literally talking about you.
Look man, all Im saying is what language you should use is matter of personal preference. If you prefer Windows to Unix or vice versa more power to you. Dont make people feel inferior just because you like one tool better than what they use.
The only thing I would make someone feel inferior for is using a tool that's wrong for the job just because of 'personal preference'.
Besides, that's not what you're saying. Your comment was pretty well flat out saying functional programming is useless and people only do it to look smart. That, clearly, is a load of crap.
