I don't think you have any idea how absolutely horrendous this would be if true. A judge, let alone a SC judge is supposed to interpret the constitution to the best of his ability. What you are suggesting is that instead, these judges let their decision be ruled by their personal feelings. If that were true they are wholly unqualified for their position.
What I think is going on is that this decision is a direct result of the type of people the federalist society has put forth to the SC. The originalist idea of the constitution has a major flaw in the sense that it interprets the constitution so narrowly. Interpreting something on the narrow basis of what is in a document written over 250 years ago has by definition the flaw that the writers of the constitution couldn't fathom every issue arising in the future. This leads to the SC judges making decisions that are so out of whack with what is right that they will cause harm. "A strict observance of the written law is doubtless one of the high duties of a good citizen, but it is not the highest. The laws of necessity, of self-preservation, of saving our country when in danger, are of higher obligation. To lose our country by a scrupulous adherence to the written law, would be to lose the law itself, with life, liberty, property and all those who are enjoying them with us; thus absurdly sacrificing the ends to the means." Thomas Jefferson.
So instead of owning up to the fact that the Republicans want these kind of justices on the Supreme Court that will make decisions that will be unpopular to the point that the public might actively vote for Democrats. You are trying to put the blame for these decisions on Democrats.
You rather claim a judge is unqualified than take responsibility for putting them up in the first place.
