No, the decision directly impacts and indeed does nullify the 14th Amendment. Freedom of speech does not trump the 14th. No provision no matter the numerical order may trump another.
Amendment #9:
If the corporate supercitizens' [illegal as per the 14th Amendment affirming equality] "rights" infringe on the rights of others, as per Amendment #9, those "rights" are not rights but rather torts.
Wealth in the modern age moreso than ever is about who runs the place. This can be demonstrated with statistics. Allowing those with inordinant wealth control the destiny of the United States is class descrimination. There is real and viable class descrimination going on with the SCOTUS decision and it is, again, in violation of the 14th which assures equality and that others MAY NOT disparage the power of another.
And further, the 14th allows Congress to trump the SCOTUS. It is specifically provided due to good foresight that nine people may not oppress the rights of 300 million.
Like I said, if Freedom of Speech has been perverted to include suppressing the de facto power of citizens to reach full life, liberty and the pursuit of happiness in a state of full equality to the one doing the free-speaking, then the 14th Amendment must be therefore repealed. Just because McCain and his lawyers were too dumb/ineffectual to read and interpret the last line of th 14th Amendment does not negate its truth and impact. Congress may simply declare to uphold the 14th and deny citizenship "rights' to corporations in the same act given that aggregations of wealthy people intent on the bottom line over respect even of country, may not oppress the rights of singular less-wealthy people or nonprofit groups of people intent on preservation of the Constitution and affecting their destinies via their power to have their voices heard over louder ones to elect representatives that they feel will help them reach their destinies.
They may just lump it all in. The Supreme Court may then only I-N-T-E-R-P-R-E-T that act in the due course of its responsibilities to do so.
