Massachusetts passed a law forbidding any public utility from encouraging a pro-nuclear energy position in utility advertisements or in billing information provided to customers. Is the targeting speech protected under the freedom of speech clause

Targeting speech is protected by the freedom of speech clause of the First Amendment of the United States Constitution.

Explanation:

It clearly states that

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof, or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances."

The above amendment guarantees the freedom and the rights of individuals to speak freely. Kindly note that an individual under the law may be:

Human or a Natural Person or a Physical Person. An example of a Natural Person is the person reading this or the person who wrote it. Legal, corporate, or juristic. An example of a corporate is an organisation such as is referred to in the question. The Public Utility Companies are corporate individuals and are beneficiaries of the freedom of expression or speech afforded by the First Amendment.

Cheers!
