Don't know about Germany but in Poland the left seems to be totally fixated on genital issues
That sounds like the Razem bourgeois left rather than the SLD workers' left.
Other countries have the same split too. I prefer the workers' left, however they really do refuse to evolve sometimes and get stubborn. The problem with grassroots organisations ids that they are resistant to change.
If they could only somehow break this magical fixation on genitals and concentrate on traditional leftist aims, they would gain much more support.
I kind of agree, however LGBT (at least the first three letters) isn't about genitals. It's about people iving a decent life without hassle from individuals and sectors of society who have unwanted same-sex 'ueges' and wish they didn't, translating that to hostility and exclusion.
Socialism is entirely about workers' control over the means of production and getting the full fruits of their labour. As long as the right wing is infused with bigotry though, the blue haired and tattooed people will stand with us (or claim to) and we will stand with them.
