Why won't Republicans in the US accept that socialist programs do not make you a socialist?

They don't read, they don't know the history of western civilization, they do not understand deep concepts and so they react almost chemically to loaded words like "socialism" with ignorance and extreme prejudice. The do not know, and they do not want to know, the underlying truths, they just want to fight with us about the labels.

maybe they dont want to accept it

--  Those item you mention are NOT socialist programs. They are NORMAL "social reformist policies" that all governments perform for their people, no matter what the political views of the government are. A government can be extreme right wing fascist through to extreme left wing communist.

--  FDR was a right wing Democrat, but his domestic economic policies were excellent and helped take the US out of the 1929-1940 "Great Depression". His domestic social policies were just as right wing, bad, and even racist. His international policies were good.

dependence on the government and systems that disincentivize personal achievement rarely produces anything good...whatever you may want to call it...

Shhhh - you can't use that word anymore -

Why don't you understand we know what socialism is and reject it.
