My hon. Friend is right: we desperately need that protection.
Other questions are likely to arise, such as whether the expression of a view on the superiority of opposite-sex marriage to same-sex marriage will be regarded as resulting in detriment to a particular group of people—namely, those who are homosexual or who are raised in families in which the parents are in a same-sex marriage. The answer is quite possibly yes. There is therefore likely to be a chilling effect on freedom of speech in particular contexts. The case of Smith has already shown a marked move in that direction. He was, as the hon. Member for Gainsborough (Mr Leigh) said, deemed to have discriminated against same-sex couples after he wrote a comment on his Facebook wall. Surely hon. Members do not intend there to be such a chilling effect on freedom of speech.
One of the ways in which this can best be addressed is by putting the Secretary of State’s reassurances in the Bill.
