What to say against gay marriage

1. Marriage is eugenic, feminism dysgenic.
2. More female MPs proportionately will support gay marriage than male MPs, calling into question their moral judgment and ability to think rationally and independently.
3. The fact that more female Tory MPs will support gay marriage than male Tory MPs is evidence of their moral judgment and ability to think rationally and independently.
4. Our political classes do not respect marriage.  
5. Our political classes do not know how to respect marriage.
6. If our political classes respected marriage, they would see the necessity of privileging married couples over unmarried couples.
7. Currently, not a single political party you will have heard of proposes privileging married couples.  
8. Marriage is for the rearing of children and so is exclusively for male-female pairings who are not in the prohibited degrees of consanguinity capable of procreative sex. 
9. Just because there are childless married couples does not detract from the original nature and purpose of marriage.
10. Catholics could have their marriage annulled (ie treated as it never happened) if one of the couple is infertile, which demonstrates the original purpose of marriage, which is to have children.
11. Gay marriage is immoral because it is not necessary.
12. Gay marriage is not necessary because same-sex couples already have the civil partnership, allowing them to take free of inheritance tax which starts at 40%.  
13. It is not necessary in the long-term national interest to legalise gay marriage.
14. It is destructive to the long-term national interest to legalise gay marriage because if gay marriage is an option then more people will avail themselves of it.
15. If more people avail themselves of gay marriage then there will be fewer children being born to husbands and wives.
16. If there are fewer children being born to husbands and wives then there will be a labour shortage.
17. If there is a labour shortage more immigrants will be allowed in
18. If there is even more immigration people will get even more alarmed and resentful causing social unrest and anomie. http://en.wikipedia.org/wiki/Anomie
19. The reason why married couples should be treated as a degree above same-sex couples, all things being equal, is that married couples are the ones whose children are most likely to be brought up in an environment that produces well-adjusted adults capable of becoming useful citizens.   
20. Same-sex couples do not produce offspring with their civil partner.
21. Same sex couples do not undergo the sacrifice, burden and inconvenience of rearing the next generation.
22. If same-sex couples were capable of sexual reproduction only then would it be moral to have gay marriage.
23. It is as well to acknowledge that it was feminism that was the thin end of the wedge that led to gay marriage.  For some reason, most women do not mind about gay marriage.  It is either because marriage was the invention of a man and they spitefully wish to destroy his creation, or because they are too stupid and irresponsible to grasp the pivotal role of marriage in regulating human relations.
