Considering that younger peoplee are more tolerant of homosexuality, that sort of strategy is going to wear thin and kill them in the long run. The under 30 crowd is going to be replacing the less tolerant, and the least tolerant will be dying off. "Latinos" may be a growing segment of society, but they aren't especially less tolerant on this issue than average. Further life examples, including in the media, will continue to break down prejudices.
It's going to take a lot of work to outstubborn them, but a message of love and liberty can be more durable than a message of hate and control.
