I don't . You do. Ergo you contradict yourself.
I think you wonder why I switch from talking about cause and effect to PSR. I don't feel like one of the boards Mr cause and effect and don't actually mention it that much. This is because one rapidly gets caught up in some pointless debate about the Kalam cosmological argument getting painted as believing everything has a cause.
I rather like to talk about contingency and necessity.
The necessary being doesn't have a cause like a contingent thing but like everything else is open to the principle of sufficient reason. The argument from contingency provides sufficient reason to posit a necessary being in the strongest of terms.
If you are against this logical termination of all hierarchies of contingency and causation then how can you be anything other than for infinite regression? I don't have an answer to that but I'm certainly ready to listen.
On another point, do you consider yourself antiphilosophical.
