The greatest threat women face is the online spread of misogyny by predator-influencers and via algorithms - even onto blank accounts set up as those of 24yo men, as in the article below.

Boys and men are being radicalized into misogyny by white men. Trans people & immigrants are not the problem.

Meta just paid the lowest effective federal tax rate in its history.

Thanks to tax breaks and loopholes, it avoided $13.7B in 2025 federal income taxes.

But now it's planning to lay off 10% of its global workforce (8,000 people) by May 20 — with more job cuts later this year.

Trickle down hoax.

If Meta adds face recognition to their “smart” glasses, it would force their panopticon onto us all.

Two lines of three dimensional sans-serif letters colored in gradients of blue and purple reading ‘Maybe it will/Happen today’. Above the ‘y’ in’ today’ and with its bottom point nestled neatly into the fork of the letter it’s a similarly dimensional golden pentagram with little flares of golden light glinting off its vertices. The entire lockup is superimposed over a glittering rainbow as it all streaks together through a black void.

#RISEUP We must be what they fear. The #USA is an evil Empire of corporate interests. There is no republic, no great leader coming to our rescue. Just regional managers as far as the eye can see.

Newly discovered bacterial defense system challenges genetic code’s central dogma. Image: In a newly discovered bacterial defense system, paired strands of DNA (orange and cyan) are synthesized by two enzymes: One (yellow) uses an RNA template (beige) to guide the assembly of the nucleotide bases that make up DNA, while a second, highly unusual enzyme (light blue) uses its own amino acids as a template."
