Well, my personal mission statement is that we want marriage equality in all 50 states. We want it not to be a state-by-state issue. We don't want it to be something the majority is voting on. I don't think the civil rights of any minority should be in the hands of any majority.

As an actor, you just want to work, and then you just want to be on a show or have a job that you love, and you hope that job will last - those things have happened. To have that platform to then talk about something that is very personal to me like marriage equality, it feels like a gift. I try and really respect that voice and not abuse it.

And think of how we challenged the idea of a male dominated Parliament with All-Women shortlists and made the cause of gender equality central to our government. We were right to do so.

Scotland is my country, the nation that shaped me, that taught me my values. A nation whose achievements inspired and inspire me, a community whose failings drive me - drive my overwhelming desire to fight for social justice and equality.

There needs to be radical development in equality law to create the environment to allow women to stay in work.
