To answer your points (yours are bracketed):
[We ridicule him, regarding the colour of his skin, his hair style etc, etc.]
It's because his skin colour and his hair ARE ridiculous. A man in his 70s who spends longer on his hair and make-up than Lady Gaga is up for ridicule.
[We ridicule his wife and family, yet had only praise and admiration for the previous President's wife and family.]
His wife stole parts of her FLOTUS speech from Michelle Obama. That's where the ridicule started. As for the rest of his family - I would lay money that most ABers couldn't even name one, let alone ridicule them. The reason why the Obamas as a family were praised and admired is because they conducted themselves with dignity.
[We condemn him for speaking the truth about some Mexicans, when he says they are rapists and murderers, while we ourselves are reluctant to condemn some of our Muslims even though they have been proven as murdering terrorists etc.]
Reread what you've written - it doesn't make sense. What WOULD make sense is if we condemned him for 'speaking the truth about some Mexicans' whilst we ALSO 'spoke the truth' about some Muslim extremists. Because that would make us hypocrites. Furthermore, he did not say SOME Mexicans. This is what he actually said:
"When Mexico sends its people, they're not sending their best. They're not sending you. They're not sending you. They're sending people that have lots of problems, and they're bringing those problems with us. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."
It's the other way around. He's saying that some Mexicans are good people, which means that most are bad.
[We also raise petitions so as to get his arranged state visit to this country banned, yet in the past have accepted state visits from some of the world's worse despots.]
That's true, but if you think of people like Nicolae Ceaușescu, Mobutu Sese Seko, Robert Mugabe etc - they all came to the UK years before the Internet and social media. We also did not have the
https://petition.parliament.uk during these times. Money on it - if Mugabe planned a visit to the UK, he would be petitioned.
It's these channels which allow people a voice now. A voice that didn't exist in the 70s, 80s and 90s.
[What kind of message does this give out to, not only the President of the USA, but also the millions of American people who voted him in power, why should they be tolerant to what must seem to them as such a nasty little country as ours?]
It gives the message that along with millions of ordinary Americans that we agree with them, seeing as Trump has the lowest approval rating for any US President...in history.
