You're absolutely correct there. My issue is that I feel like so many of us are almost giving in to the desires of those that spread misinformation, and becoming completely cynical towards anything that's shared online. A healthy amount of skepticism is required. Asking yourself "what does this person gain here if they're lying" and if that answer is "some notes on tumblr" then I'd personally rather choose to believe them. To instead get to have the positive feelings that post provides. Rather than dwell on it and believe that all of humanity are dishonest and disingenuous.
My son's school has recess up to grade 7, but I think grade 5 would be a better guess for learning the meaning of the word lesbian and also the quality of the handwriting. This is also about the time I recall girls and boys starting to have crushes.
