I agree totally with the point you are making about not giving the media any excuse to link Motherwell to sectarianism and bigotry;
BUT; I do not think that anyone could, or would, be able to point at a Scottish team flying Saltires at the Scottish Cup Final and describe that as sectarianism or bigotry.
The Union Flag would probably play right into their hands though, regardless of colour scheme.
On the subject of Saltires, folk saying that we don't fly them week in week out are correct, but playing devil's advocate, we don't play in cup finals week in week out, so if people want to make that extra effort and take a Motherwell flag that they normally wouldn't then I think that's fair enough.
Cannot agree more about the points being made about doing this to show support for Motherwell as opposed to winding up Celtic fans though.
