Why do iPhone users tend to look down on Android users?

I extensively follow mobile phones. I know that iOS tops at times and so does Android. But my liking tends to lean towards Android. A lot of people I meet or even friends who bought iphones often tend to hold me in contempt when that see me using an Android. I honestly like both but spending over 70000 rupees on a phone is too much for me. I'm happy with my 15000 worth phone and it works perfectly for me. But somehow thesevpeople are on mission to make me hate Android. I mean what's going on in their head. Why can't they just accept that both are great in their own ways?
