December 13.
The two cows

Today is St. Lucia's day! I picked this tale, from the Hungarian Roma tradition, accordingly.

A poor man has two cows. On Lucia's night he goes out to guard them from wandering witches. Because on this night animals can talk, he overhears them complaining about their food and the way he treats them.
After that the man pays more attention to caring for his cows, and teaches others to do the same.

Today, scottish Arch-TERF JK Rowling announced she's funded a competing rape crisis centre in Edinburgh that will only serve cis women, apparently as a fuck-you to the existing Edinburgh Rape Crisis Centre, which has a trans woc CEO and has endured months of harrassment from TERFs to the point of temporary closure. Please show some support to the current trans-inclusive ERCC if you can:

I remembered to put the queer butterfly emojis onto my itchio page, so everyone has easy access if you wanna add them to your instances! https://frazzledbrynn.itch.io/queer-butterflies #BrynnDraws #Art #Emojis

#Mastodon has a LONG way to go to on Black #inclusivity. This is surprising because it’s appropriately focused on #accessibility and #LGBTQ+ inclusivity. We all need to uplift #BlackMastodon in every way we can. This will make Mastodon better and create a sanctuary for the Black community. Call out, fight, and report all micro-aggressions/racism witnessed here. Boost posts/accounts of Black Mastodonians. Use your #privilege to be a voice. This is our #responsibility. We’re #StrongerTogether.

A joke that probably might’ve been done before but thanks to my roommate for the suggestion

Let's stop treating vaguely medieval Europe as a neutral or default setting. Call your European fantasy European. If you want it to be generic examine that and step a little bit away from the assumptions layered in the paneuropean vaguely white base.

What does that mean for your world? I don't know! That's the exciting bit!
