Irish serfdom under the English squirearchy was unfree, coerced and explotative. People fled that by selling themselves.
I don't think we need to minimise that. It wssnt chattel slavery, people were not directly bought as commodities, they were not packed like tetris blocks on slave ships. Serfdom is still a form of slavery, as is indentured servitude.

Edit: It isn't laundering racism to point out that things that arent chattel slavery can still be slavery. It is absolutely some kind of racism adjacent conspiracy to invent a theory of Jewish domination of an Irish slave trade. But pointing out that serfdom is unfree isnt the same thing.
