Young mom with purple hair and piercings judged by older moms at the park

Just gonna rant because it seems that older moms (not all, but quite a few here in Reno) are still judgmental prudes to anyone that doesn't fit their standards. I am a young mom, and I took my son, baby sister, and older sister to the park with me yesterday. We had a blast, it was awesome. But I couldn't help but notice that some older mothers kept looking over at me and whispering and shaking their heads. Did they dislike my purple hair? Or is it the piercing on my lip? Or maybe it was the multitudes of earrings? Or was it just the fact that I am young and had two kids with me? Either way, it was pissing me off. Who are you to judge how I look to factor in how good of a mother I am? I was playing with my baby boy and sister. YOU on the other hand were watching from a far with babies the same age! Keep judging me based off my looks and using it to determine how well a mother I am, I'll just keep changing myself to how I like because I am an awesome mother with an awesome punk rock attitude.
