I am very fortunate to be someone who had very positive breastfeeding experiences. This is notable because not everyone does and because I breastfed for a collective 38 months.

In talking to other breastfeeding moms, though, I've come to realize that while mothers nursing children of any age can take a lot of crap for their choices, moms who nurse children past a year get particularly nasty comments. The awful things people say when you're extended breastfeeding can be cruel, hurtful, undermining, and just plain old annoying.
While I can't make stop all the judgmental people in the world from making condescending, hurtful, or inappropriate comments and hurling them in your direction (though I'm trying in my attempts to normalize breastfeeding!), take comfort in the knowledge that lots of other mamas know how you feel and, most importantly, that the negativity of others tells you a lot more about someone's attitudes about women's bodies and motherhood than it does about extended nursing. Should so many breastfeeding women be able to say they've been judged? No. But there's power and comfort in knowing you're, for better or worse, not alone.

Every now and then, usually from a stranger or near-stranger on the internet, I'd get an obnoxious display of histrionics. But reaching into my own extended breastfeeding experience (and borrowing from some friends) I've encountered some real gems:
