You are being dishonest because examples of the GOP pandering to white voters are well-documented and easily accessible. Either you never looked, in which case arguing at all is dishonest since you don't know what you're talking about, or you looked and ignored the mountain of evidence denying your view. The "script" part is likely about you shifting the goalposts. Why doesn't dog-whistling count as explicit pandering to white Americans? That isn't to say the GOP are always subtle, either. All in all, it seems pretty clear you're sealioning.
For the benefit of other readers though, I'll bite.
For instance, former congressman for Iowa Steve King tweeting about slavery [0] is pretty explicit. How about the slightly more abstruse but still pretty glaring white supremacist dog whistle [1] in response to a random Dutch guy complaining about muslims. He was in congress 2003-2021.
Of course Great Replacement rhetoric is also pushed pretty openly to rally white voters, with Tucker Carlson saying things like "demographic change is the key to the Democratic Party’s political ambitions", and congresswoman for New York Elise Stefanik running ads saying "[Democrats'] plan to grant amnesty to 11 MILLION illegal immigrants will overthrow our current electorate and create a permanent liberal majority in Washington".
Do you accept these examples or do you need the GOP leadership to issue a letter signed by all party members stating they like white people?
