Marchers called for greater equality, the legalisation of same sex civil marriages and the right for homosexual couples to adopt children.
No matter how many marches as such will be carried out, and no matter how many people turned up to support the gay pride, the Church will never approve same sex marriages.
These are what Pope Ben XVI said regarding homosexuality and gay marriage:
Although the particular inclination of the homosexual person is not a sin, it is a more or less strong tendency ordered to an intrinsic moral evil, and thus the inclination itself must be seen as an objective disorder...
-- Letter to the Bishops, 1986, quoted in National Catholic Reporter
Above all, we must have great respect for these people who also suffer and who want to find their own way of correct living. On the other hand, to create a legal form of a kind of homosexual marriage, in reality, does not help these people.
