The LGBT people are certainly a minority but hardly privileged. For centuries society has condemned and persecuted them frequently to the point of execution. If they had friends to get where they're at, then I must applaud and encourage those friends. If there are other minority groups whose rights are being denied then let's get on with correcting that.
A fairly large block of my fellow Christians have what could be called an entitlement mentality. For a great many centuries we Christians have had things our own way and have controlled society to such an extent that we have been able to impose our own agenda without challenge. However, when minority groups started demanding and receiving rights that they had previously been denied, rights that Christians held all along, these same Christians felt threatened and some even claimed that they were being persecuted. Rights and freedoms are not part of a zero-sum game. Expanding them does not thereby reduce them for some other group. For example, extending marriage rights to homosexuals has not reduced the rights of heterosexuals in the slightest way. In reality Christians have lost no rights and are not threatened in any meaningful way. In Canada and the USA Christians are certainly not being persecuted.
