I am incharge of my works social media. I had looked up random holidays (example:chocolate day, ice cream day, flag day) so searching the internet for a random holiday on this specific day I found Juneteenth before BLM riots and guess what in the definition it was only a Texas kinda thing. So I didn't use it at all because it did not apply to other states for celebration as the liberal at my work totally agreed. To circle back to this being clown world we picked juggling day ?. Labor Day is always covered. Just need a post for that day years back

So why doesn't the Alamo get celebrated by everyone once a year?

Because it doesn't fit the narrative.
