From here:

A senior teacher has been suspended from his £50,000-a-year job after he complained that a training day for staff was used to promote gay rights.

Kwabena Peat, 54, was one of several Christian staff who walked out of the compulsory session at a North London school after an invited speaker questioned why people thought heterosexuality was natural.

The presentation was given by Sue Sanders, a co-founder of the Schools Out organisation which campaigns for gay equality in education.

According to Mr Peat, Ms Sanders, herself a lesbian, said that staff who did not accept that being gay was normal had ‘issues’ they had to deal with.

She started promoting homosexual lifestyles and suggesting those who had objections should sort out their prejudices. She said, “What makes you all think that to be heterosexual is natural?” It was at that point I walked out.’

By saying “What makes you all think that to be heterosexual is natural” one assumes that Sue Sanders is not about to make the case for heterosexual sex being supernatural; the point she is attempting to make is that, in the view of equality commissars, a homosexual act is no more contrary to nature’s intent than a heterosexual one. Little argument is given for this: we have already moved beyond discussion to enforcement.

Why might homosexual activity not be nature’s norm? The reasons don’t seem to be beyond the reach of common sense:

First, the plumbing is wrong.

Second, for those who believe we are here through natural selection, the homosexual gene – if it exists – is a dead end gene that eventually should be selected out; hardly a case for normality. The fact that it has not been either means we haven’t given it enough time, or we are not here through natural selection.

Third, if there is no homosexual gene, gayness becomes a lifestyle choice; it has no more claim to normality than any other unusual lifestyle choices. Most lifestyle eccentrics are proud of their peculiarities: to canvas for recognition of normality for freely chosen foibles would be self-defeating. No self-respecting eccentric wishes to be reduced to hum-drum, mediocre normality.

Forth, to bring in religion, all major faiths maintain that God’s design is for heterosexual sex within marriage – I am excluding Western Anglicanism since it isn’t a major faith.
