Rewatched some Star Trek tonight.
Still wild how a show about warp drives and weird nebulae ends up teaching the cleanest lessons about being human.
Every episode says the same thing in its own way:
‘Be curious. Be brave.
…Try not to fire phasers unless you really have to.”

Spent 5 hours imaging the Lobster Claw, and struggling to find an edit I like. Then on a lark I spent 10 minutes on the Orion Nebula (60 10 sec subs, stacked in PixInsight, processed with PI and Affinity). So what do I spend my time on? This:

Remember when Texas Dems broke quorum & in response TX AG Paxton & Gov Abbot demanded their arrest & removal from office?
Under Speaker Johnson, Congress has been in session only 12 of last 100 days, absent since Sept 19, & he still won't swear in Rep-elect Grijalva.
Rules for thee but not for me.

The idea that President can negotiate/dictate bilateral “deals” by using the full force of the federal government to punish and humiliate his perceived enemies goes against the whole idea of the rule of law. That should be the story, rather than normalizing this authoritarian behavior.
