I don't know about the March but I do know about those involved in the OAS talks and the issues that do worry parts of the society, which include abortion. However it's not my goal to discuss that. It's a topic OAS is touching.
It is indeed a goal of yours. Note that you mentioned it again.
On LGBT: it's most probably not of my business what someone else decides about his or her or its life. I have my opinion based on my Christian conviction and I believe that they (my convictions based on the bible) are ultimate truth, but I can't insist or force anyone to also believe that, I can only proclaime it. However, when groups of people think their way of thinking is the correct way and feel the need to teach my children that the LGBT lifestyle is normal and natural, I believe I stand in my right to voice my opinion on the matter. I don't really care if you think you are actually a woman and dress like one or even have your body changed like one, but I do oppose if you want to teach my children to discover their sexual identity, poisoning their mind with thoughts that are not natural. In the same way, it's not of my business if you are gay, but I don't want my children to be taught that being gay is normal, because I believe it's not. And yes, that's also based on my convictions, but tolerance goes both ways.
Tolerance used to mean that you shouldn't be judged on your opinion, way of life etc., but nowadays it seems to mean that you can't state your opinion if it goes against what the liberals say.
So, while I have no say in how you live your life I maintain the right to voice my opinion on matters that involve the society including my family and my faith. you have the right to call x sexual orientation normal and acceptable and I have the right to call it counter natural and something I'd like to inform my children about in the way I deem appropriate.
