Croatia supports the rights of all its citizens, straight or gay. There is to be no discrimination based on one's sexual preference.
A man can love a man, a woman can love another woman; but legally, in Croatia, if someone wants to get married, that someone must marry someone of the opposite sex regardless of which gender they love. After all, though love is a most desirable component of marriage, it was never the reason why the institution of marriage came about in the first place.
Croatia showed where their true beliefs were in response to a marriage petition which ended up carrying some 750,000+ signatures. The petition read,
"Do you agree that a provision be incorporated into the Constitution of the Republic of Croatia which defines marriage as a lifelong union between a woman and a man?"
Croatia, a country of 4.4 million
Nearly 90% of the Croatian populace is Roman Catholic. Their leaders encouraged them to vote "yes" in the referendum that would define marriage as a lifelong union between a woman and a man.
Croatian cardinal Josip Bozanic is quoted as saying,
"Marriage is the only union enabling procreation. This is the key difference between a marriage and other unions."
In spite of gay marriage supporters marching in the capital to promote a "no" vote against the referendum and in spite of influence from Croatia's president Ivo Josipovic and Prime Minister Zoran Milanovic in being against the amendment, more than two-thirds of the members of parliament in Croatia showed they were for the plan.
The people of Croatia voted overwhelmingly in favor of traditional marriage, and Croatia's constitution will be amended.
Croatia is the 28th and latest member to join the EU. Thus far, the EU hasn't commented on the outcome of the referendum vote.
Croatians back constitutional ban of same-sex marriage “Even though a proposed change to the constitution doesn’t take away any existing gay rights, it will be seen as a negative moment, and a setback like this can act as a catalyst that mobilizes the gay community.” (Paul Barnes, the head of communications at the Gay European Travel Association)
