New type of marriage in UK

Homosexual couples are more and more common, even the countries and law slowly getting more pleasant for homosexual part of society. Yesterday, UK gave permission to same-sex marriage. We have to remember that the marriage law was the final victory in a long battle that has secured the same age of consent as heterosexuals and the right to adopt. England and Wales are among 15 countries as well as parts of the United States and Mexico that allow same-sex marriage. The Netherlands was the first in 2001, and last year Brazil, Uruguay, New Zealand and France also joined the list.
What about Poland? When we take such a step in legalising homosexual? Do we really need it? Are we tolerant enough?
