Dismantling the social institution of marriage

What we observe currently in our world is that one social institution dismantling the other. Of the many, the social institution democracy is seriously eroding the social institution of marriage. For the sake of democracy, governments of advanced countries are making mistakes for being reluctant on formation of lesbian and gay marriage institution that would endanger the continuity of generations in our planet.

Last year when I was in London, a British friend of mine told me that a lady working in one of a municipal administration in UK has been fired from her job for her unwillingness to execute contractual agreement formalities for gays who had come to her.  It seems that governments fail to understand the gay and lesbian marriage institution affect the vast majority socially and morally.

Advanced countries are dismantling the marriage social institution not only in their country but also crossing i overseas. For example, gays in Malawi, Zimbabwe and other African countries! I think if democracy is to dismantle the other good social institution, better not to be democratic!

I think advanced countries are committing a serious mistake just as they did for global warming as this new marriage institution deters the continuity of generation! Is it not?
