Why do some moms that birthed "naturally" try to shame those who didn't

In my opinion giving birth is hard and every mom deserves a pat on the back for going through it. Whether it was a c section or vaginally. Whether you had an epidural or other medications or not.  I just have gotten a lot of crap from people when I tell them I got an epidural. One mom said "Oh I bet you had an easy labor then huh?" I just laughed it off but I felt like saying "Uh no bitch. The contractions hurt like hell and I went to 5 cm without any epidural." But I'm just not not the type of person to say something like that out loud lol.
Edit: yes Katey I know not all "natural" birth moms try to shame others. It's completely fine to be proud of it but it's another thing when you're rude towards those of us who wanted to be medicated during labor
Frieda: Lovely comment however birthing natural doesn't always come with no tearing. My mother got 2nd degree tears when she had my brother and it was a natural birth. Also I had no tears with an epidural.
