Let's not misconstrue this. Statutory laws can be revised if they are deemed unconstitutional. The crux of the matter here, particularly with reference to the Civil Rights Act, is whether you truly condone the idea of enabling discrimination. Debating the legality of a law is one aspect; aligning with its fundamental purpose is a different conversation.
You appear to be taking for granted there's a conflict between this decision and the fundamental purpose of the Civil Rights Act. That depends on what the fundamental purpose of the Civil Rights Act was. If you're assuming its purpose was to end discrimination, no, I don't think it was. Its purpose was to end discrimination
in public accommodation. I.e. its purpose was to take away the keys to a bigot's motel and hand them over to a weary traveler. This was because the government liked weary travelers better than bigots -- and rightly so. But its purpose was not to take away the keys to a bigot's
mouth and hand them over to whom the government liked better. Somebody else's mouth is not a place of public accommodation, and I don't see any evidence that the Congress that passed the Civil Rights Act intended to make it one.
The First Amendment stands as a safeguard for the citizens,
not against each other, but against potential
governmental overreach. It ensures that our freedom of expression remains unfettered
by the government, even when such expression might be perceived as offensive or inflammatory.
Contrastingly, the Civil Rights Act operates as a bulwark against discrimination in a wide array of social and economic realms. Conceived with the aspiration to eradicate bias-based conduct, it expressly forbids discrimination rooted in race, religion, sexual orientation, or national origin. The notion that some individuals perceive themselves as unprotected is indeed puzzling. Regardless of one's origin—even if hypothetically hailing from the farthest reaches of the cosmos, whimsically referred to as 'planet numskull'—every individual is shielded from discrimination predicated on race, religion, sexual orientation, or national origin.
TLDR :
1st Amendment protects the people from the government
Civil Rights act was crafted with the aim of eliminating prejudiced practices
There exists no inherent contradiction here; rather, it's an issue of misinterpretation. Some individuals seek to camouflage their discriminatory practices under the guise of exercising their First Amendment rights, despite the fact that these rights do not confer immunity from the actions of other citizens.
