Someone explain to me why im moderate and whacko left is a bad thing

Hi guys! So, i am a Bernie supporter, but of course with the way our whacko left works, i am literally considered "right wing" on this subreddit. I dont understand why this is the case. I am not a socialist, im not a resident in the 6th grade, im not a 15 year old whacko who wants to kill white people, or destroy America, im not an anti semitic or racist, i am a Bernie supporter, but not with the radical ideas this chamber advocates for. When this chamber is going batshit crazy about 3.5 trillion without any solutions or proposals, i am moderate, when this chamber is supportive of AOC and pushes her forward, i am moderate. When this chamber tries to cancel Bernie for not doing enough and is asking for his challengers, or calling him "stupid" or saying "he is just another elder democrat" when i am a bernie supporter and wont accept it, i am a moderate. I am a moderate socialist whos idea of socialism is capitalism with a human face, and i support Bernie because he is the moderate socialist whos idea of socialism is capitalism with a human face, but somehow im a moderate and im told to go to a neo liberal subreddit. Someone explain to me why this is the case
