Life would get pretty boring if everyone was exactly the same.
Quite honestly, if you took a poll, the majority of people who fish just don't get fly fishing. Why would anyone spend all that money on a fishin pole and some fancy string. I use a $9.99 Ugly Stick with a jig and pig and catch a bucket full every time.
The opinion of others should not deter anyone who enjoys fly fishing from doing so, and it doesn't make sense to get upset if you can't convince others to your way of thinking.
For the record, I can't imagine why anyone would voluntarily eat broccoli.
