Stop telling people how to vote
Oh ffs. She's set up a page for people who want to keep the Tories out at all costs, and might wish to vote tactically to achieve that. She's not telling anyone who doesn't want to know, how to vote. If people aren't interested, don't look at the website, it's not for you.
I'm sure there's a website out there with Inverness bus times on it. Do you here the people of Cornwall say "stop telling us the Inverness bus times"?
Probably not, because the people of Cornwall aren't interested, so aren't looking at the website.
