Lulu Press, Inc., which had been publishing my books (most of them listed on the sidebar but even those in Spanish), has nuked my account. I have communicated with them. It looks like termination has to do with what they call ‘Questionable content’:
This includes content that Lulu’s deems to promote… discrimination against others based solely on race, ethnicity, national origin, sexual orientation, gender and gender identity…
This means that I should try to start a small publishing house (like e.g., Counter-Currents Publishing). Otherwise, if I go for example to Amazon for another print-on-delivery service, they may also terminate my account after some time (as happened to Arthur Kemp’s Ostara Publications).
