The problem is that oftentimes, those with the opinions cited in this article aren’t just having their opinions and their way of life; they are actively trying to PREVENT people from having their lives. When anti-LGBT activists promote anti-same-sex marriage laws and try to ban same-sex couples from having children, it’s no longer just having an opinion; it’s an attempt to be OPPRESSIVE. Therein lies the problem. The LGBT community and its allies want everyone to be able to live their lives equally, with similar rights and freedoms. The side promoting opposite sex pairings and parenting only are trying to impose on the other side’s rights. That’s the difference, and that’s the problem, and that’s why it’s impossible to just let these people “have their opinions”: because they want to DO something with those opinions, rather than simply have them.
