ANSWER - I think most people, witches or not, get a little fatigued on occasion by the apparent superficiality of others. Note the word apparent.... The trouble is not that people are by their nature superficial but that the parts of ourselves we are willing to share with others are the parts with the least depth. You are right that social media often show the least worthy side of human behaviour. But social media is a very impersonal way of interacting. If you want to see more of people you have to work harder at it than just switching on your computer
Scratch below the surface and you will find that most people have depth and a meaning to their lives that goes beyond the shallow confines of popular culture. But as I say - you have to work at it - people will not trust you with their innermost thoughts and feelings if they are fearful that they will be condemned and judged. I'd suggest telling people that the things they care about are "crap" isn't the best starting point for forming more meaningful relationships...
When we are young we have an understanding of our own worth but as we become wiser we also start to appreciate the worth of other people. This is the wisdom of maturity - we begin to understand that we are not alone in having thoughts and emotional depth, we are in fact just one of many (most? all?) sentient and complex humans who do. I am afraid that writing off sections of humanity is both short sighted and to your own detriment. How do you expect to grow if you are willing to learn nothing? How do you expect to attain humility if you value nothing?
I do not believe I have ever met anybody, witch or otherwise, who has not been able to teach me something. Nor have I ever met anybody who was not better than me in some way or at something. If you open your eyes to the fact that the world is filled with people who can teach you and you can swallow a bit of your arrogance you will be in a better position to understand the worth of others and as a consequence you will not feel so alone. Putting yourself on a pedestal separates you from those who might have real wisdom to share with you. I'd venture you'd also be enjoying life a lot more if you hopped off your self built pedestal and tried to mix with people without believing yourself to be superior to them.
Incidentally you also make the assumption that witches are in some way better than other people. I've met some pretty shallow and stupid witches and I'd dispute the fact that practising the craft makes you special in any way. Witches are just like anybody else - a hotchpot of good/bad/ clever/stupid/ kind/malicious. There are witches who will tell you they are better than anyone else but these are people to avoid. Generally with witches, as with anyone, the people shouting from the rooftops how great they are are spouting hot air.
Now stop being so self indulgent - get out there and make some friends.
