These people do not want equality - they think they alone can modify the meaning of words. “Marriage” has always meant man & woman.
It was never about equality or expanding “rights” - it is about taking rights away from others. Witness their behavior with the bakery owner, photographers, etc. If the business doesn’t want to cater to their “pretend” weddings, they don’t just leave them alone and take their money elsewhere and pay someone who will, no - they harass them out of business - want them discriminated against because they have different beliefs than their own.
