You may consider race baiting a standard or acceptable form of politics but I do not.
Yes you do. You voted for, admire and support Boris Johnson, who has a history of race baiting for his own political gain.
Until you withdraw you support for him and accept the damage he's done I can't imagine anybody on this forum taking anything you say or post about ethics or morals remotely seriously.
I mean, it's not really about shaking hands... the issue is that the English Trump who exploited Islamophobia for political gain actually seeks a closer relationship with the Indian Trump who exploited Islamophobia for political gain. The ad is dumb, and it's not like any other English political leader wouldn't shake Modi's hand—given how important India is for England's survival—but it's possible they might be able to produce a leader who doesn't share Modi's love of exploiting Islamophobia.
