I do try to figure out this issue. I don't understand it, fully.

Some things: my sister is now married to a woman, after 20 years married to man and two children.
She was her son's scout leader at the time her relationship started, and had to keep real quiet and worry about anyone guessing, or if she would have to lie. Her son became an eagle scout so this was a big deal.

But why march in a parade? I don't get it. Is it just the exposure to champion gay rights and end discrimination? Why don't fat people march in a parade to end discrimination against them?

And why be prevented from marching in a parade, like any other group? I'm sure there's firefighter groups, and shiner's and 4-H groups.

Is it specifically because they have a political agenda, which asks for partner's rights, and they are fighting for changes in laws that many object to?

I don't see why they should march in a parade, I don't see why they shouldn't. I just don't get the whole thing.
