DoraGora: "Any display of it which falls outside the law is already banned."
This sentence doesn't say anything. You're just saying that displays of homosexuality that are illegal are illegal.
People like GraysAnalogy would like to have mind control / speech control so that saying that homosexual acts are a sin, that homosexuality is a lifestyle choice, etc. would be illegal. We're already seeing this approach with the attempt by the gay lobby to ban aversion therapy even when voluntarily entered into by adults.
Already in Canada the gay community has required that the state fund surrogacy for gay men, i.e. state pays egg donor and gestational carrier/womb renter, so that gay men can have a child. This is the next thing that the gay community will demand here - in the name of equality.
Because of political pressure in the UK we may now receive blood from gay men - contrary to practice in Netherlands, Germany and France. Wait until the next virus like HIV comes around and spreads through the gay community. The virus will be new and so can't be tested for and, as happened with HIV, it will spread to people, including children, through blood transfusion before people realise it.
The level of overreach by the gay community is massive. I fear for what is going to happen when the backlash comes.
