No, Gay Pride Marches must NOT be protected under the First Amendment, because homosexuality is a crime that should carry the penalty of Capital Punishment, like first-degree murder. The Holy Bible condemns homosexuality as much more evil than first-degree murder.
The Holy Bible determines ultimately what is moral and what is immoral. The Law of God is the final arbiter in the world for what constitutes a crime. The Holy Bible declares homosexuality as a crime more evil than first-degree murder, and the Holy Bible is always right.
It is important to note that ancient Israel, God’s nation, ordered Capital Punishment for homosexuals through its court system at the same time that Greece, a democracy, existed and protected homosexuals. Jesus Christ upheld application of laws ordering Capital Punishment for homosexuals during the New Testament time period. Jesus Christ never shared the Gospel with homosexuals and never expressed His “love” for homosexuals, because the Holy Bible considered homosexuality as the greatest evil in the world and the most evil crime against society. There were a lot of homosexuals during the time of the New Testament, and that is why Romans 1 condemns it in no uncertain terms.
Crime is defined by a society. Unless the society submits to the Holy Bible in understanding and defining what is a crime, the society will degenerate like the pedophile, homosexual societies of Greece and Rome, which eventually fell because of the proliferation of immorality in society.
Because the Holy Bible emphasizes that homosexuality is a crime that must be punished by the laws of the land, Gay Pride Marches are NOT protected by the First Amendment. The Holy Bible is the final arbiter of what is a crime. The Holy Bible is the final authority on morality and determining crimes.
