Why are people so mean on here ?

I just mentioned my son in a question people laughed at me and judge me for being 27 having a 14 year old son. I forgot to mention he's my STEP SON. I married his mom I guess that makes him my son now. What's the big deal with being judgemental about it lots of teens have kids my son's mother was a teen mom she had him at 17. I guess I should have added more details even though the question wasn't really about my family also he calls me dad a lot more than his own father. I didn't think people would laugh and be so mean. My wife's not gonna be happy about this she'll be a Karen when she hears about this site. Why are people so mean and judgemental on here ?
