Those who want to interfere with the definition of marriage say they are being falsely and unfairly discriminated against by normal people.
That is not true. What normal people are doing is upholding and defending the truth of what marriage is, and refusing to have it discriminated against with falsehoods.
The real discrimination is being perpetrated the other way, for in denying the truth of what all married people are, the others are fiercely discriminating against them.
False discrimination is discrimination founded on a lies. Those who are denying the truth of what marriage is are pushing a lie.
I someone said, 'I want to be a lawyer; everyone has the right to be a lawyer; everyone should have that right equally; and by having a narrow definition of "lawyer" society is discriminating against me--so change the definition, Parliament', that would actually be discrimination against real lawyers, because it would destroy their profession, it would remove their unique situation and status. It would therefore be discrimination against them, it would be discrimination against what they are, using a lie.
Trumpeting 'lawyer equality' would just be putting the lie in fancy dress--making it appear valid with claptrap, with a meaningless slogan. It never can be valid, it never can have a true meaning, because lawyer is lawyer is lawyer is lawyer is lawyer. Changing the meaning of the word to mean anyone who is in a range of unlawerly situations only destroys a word; it achieves nothing in the real world except confusion.
Only those who qualify to be called lawyers may be called lawyers, and only those who have qualified have the right to a licence to practise as lawyers. To insist on that is not discrimination against non-lawyers. It is reality.
It is not a 'right' to be defined as something you are not and never can be. It is not a 'right' to have a legal licence to call yourself something you are not and never can be.
