BRITISH actor Sir Ian McKellen is supporting aggressive tactics in the gay-marriage fight. In an interview on IMRU Radio in LA, McKellen said: “We’re . . . discovering who the enemy are, and I do think we do have an enemy. It means that everyone’s got to go on fighting. And in what way you fight, well, it depends who you are . . . You can write a letter, you can talk about it to your congressperson . . . you can talk to people in bars . . . Or you can go on marches, or you can go and break windows.”
