Why do people care so much if you have an iPhone?

I'm perfectly aware that there are substantive technical differences between different types of phones. But as far as my subjective user experience is concerned, it's all the same. I'm not doing anything all that sophisticated with my phone on a daily basis. I'm running some basic apps to manage my social media presence and looking up trivial minutiae on the internet to win petty arguments with my brother.

So, from my perspective, any basic smart phone is suitable to my needs. While I'm sure that Apple and Android fans can both make fine points regarding the pros and cons of the various phones and OS's, I'm not particularly invested in that debate since my needs are so basic.

This of course raises the question, if my needs are so basic, why did I get an iPhone instead of something more bare bones. The answer is simply that it's the phone my brother has, and he attested to it's reliability and stability, things which were sorely lacking in my previous

I never knew that these allegiances were so deep, to me Android or Apple doesn't freaking matter. It's all the same BS. I just like the iPhone 6s better. F off! I'm not a Apple fanboy, I could very well get sick of it and go back to Android in the future, I have no loyalty one way or the other.

None of my friends and family care about what phone I own. They know that I have used a prepaid cell phone carrier for years and only purchase cheap prepaid smartphones.
