I don't spot, I used to fly, I don't play golf but I do, and enjoy, ballroom dancing, which a lot of people probably don't like. However, I like it, it is one of my hobbies, and I think it is very ignorant of people to run down what other people enjoy.
I don't see what spotting has to attract people to it, but at least the spotters have a hobby, which makes them much more interesting than people who don't have one for a start. What other people do in there spare time is surely sacrosanct, and should not be criticized simply because it's not what you would do!!. Each to his own. [I also adore pretty women, and that's harmless too]
