The Royals shouldn't invite Trump to the Prince's wedding.

[DemocratSinceBirth]

None of them like him anyway. It would be insincere.

1. Like he's gonna

Bring a gift that the couple would want and use.

2. Trump wants an invitation

so he can turn it down in the most demeaning way possible for both the UK, Prince Harry, and the Obamas.

3. drumpf would also try to steal the "show".

drumpf's cancer doesn't need to be spread in the UK at a Royal Wedding.

4. Is it too late to tell him his invitation was lost in the mail?

You just can't rely on international mail!

5. Problems with inviting Donald Trump to Prince Harry's wedding:

1. The wedding will be focused on Trump.
2. The news story will be that Trump and his family won't bow to the Royals, esp. the Queen.
3. Trump will give an "exclusive" interview to Murdoch's paper(s) where he finds a way to insult the Royals and Meghan (e.g., she's biracial like Obama).
4. Trump will make infuriating Tweets during the wedding week-end. (See #1.)

Feel free to add on.

7. Since it's not a British state affair...

They can pick and choose whom they wish.. No heads of state are being invited said the British press. I wonder how Murdock's news machine is gonna spin it...

9. The security will be intense enough, without adding anti-trump* protesters to the mix

It has been a while since I've been to St. George's Chapel, but the grounds at Windsor Castle are much more confined than those in front of Westminster Abbey or St Paul's Cathedral. Harry is pretty popular so the crowd control will difficult enough, dealing with those who are there to wish the couple well.

I've been in the midst of British crowds for joyous occasions (Queen's Jubilee) and political occasions (Poll Tax Riots). Those political crowds can get really rowdy. And I suspect that trump* is easily hated as much, if not more, than that poll tax.

10. Trump would cause the event to be subject to protests

[smirkymonkey]

11. Absolutely they shouldn't! Why would they?

It's a private affair, not a state affair. They hate him and so do most Brits. It would forever mark Harry and Meghan as traitors in the eyes of their people if they did.
