Perhaps this was your problem. Who is not important, what they are saying is.
You're being told you're wrong? Why? Do they have a point or does their argument break down to simply 'because' or 'because no one has done it that way before'?
If they have a point, at the very least, they probably just pointed out a problem you need to over come in the future and you can thank them for expanding your understanding of the situation.

You'll find that the vast majority of arguments that people give you have a point. Look no further than the arguments provided against Dropbox here. The real difficulty is knowing which points are more important than others.
For example, whether developing a desktop program has the potential to be the next big startup in part depends on whether or not you believe the desktop market will still be around in the next some odd years. There is no 'right' answer to that question unless you happen to be able to see into the future.

The 'because' people though, just ignore them.
