I think the real trick here is to learn how to distinguish between objections that are just examples of people not getting it, and objections that really do point up a fundamental problem you will have to overcome or find a way around in order to succeed. This can be trickier than it sounds.
A common mistake advocates for new technologies make is to fall in love with their new toy and dismiss any skepticism of its prospects as examples of cluelessness -- often with glib responses like the one in the OP, "don't hate, create" (ugh). Not everyone who comes to you with a critique is a "hater." Some of them are coming to you because they have learned something through hard experience that they think will be helpful to you. Ignoring those people can lead you to walk right into the same well-hidden minefields that have blown up countless other bold explorers over the years. So there's value in learning how to spot the one guy in the crowd of people telling you to watch where you step who's sporting a peg leg.
