Thank you for answering my 1st question.
Did you answer any of my questions? 
Do you feel that as PM, he has a responsibility to unify people?
Yes, of course, but his 2002 and 2018 comments were made before he became Prime Minister - he wrote both of those articles when a backbench MP.
Can you see how these comments can embolden Far Right groups?
If you think that a few comments written by Boris Johnson 16 years apart have emboldened Far Right groups I think you are on the wrong track. It is the left-wing/liberal media/MPs who keep repeating these comments in any case.
Looking at the Tell MAMA stats in your first link;
"In the week following that article [Sunday 5th August 2018] Tell Mama said anti-Muslim incidents increased by 375%–from eight incidents the previous week, to 38 in the following."
"Of the 38 anti-Muslim hate incidents, 22 were directed at Muslim women who wore the niqab, or face veil."
(In the annual report these are off-line incidents, mainly verbal abuse.)
For comparison - "the number of racially or religiously aggravated incidents following terrorist incidents in the spring and summer of 2017 rose to 6,000 at their height."
I assume this figure includes on-line and off-line incidents.
"from eight incidents the previous week, to 38 in the following."
Minor points:
Tell MAMA appear to have counted a 5 day week for the 'previous week' (Mon 30th July - Fri 3rd Aug) and an 8 day week for the 'Boris Johnson week' (Mon 6th Aug - Mon 13th Aug).
We are shown weekly bar charts for 1st Feb - 27th June and a daily graph for 30th July - 25th August but nothing detailed for 28th June - 29th July. July does dip slightly as a whole, but I'd like to see the individual weeks leading up to the BJ week. Not enough room on the page? Or July doesn't fit their written analysis?
Published at the same time as Johnson's article:
4th August Daily Mirror - "Muslim woman is first person to be charged in Denmark for wearing a face veil in public."

8th August Telegraph - "Rochdale grooming gang members face deportation after losing appeal."
www.telegraph.co.uk/news/2018/08/08/rochdale-grooming-gang-members-face-deportation-losing-appeal/
11 August Daily Mail - "I can't breathe. I'm itchy. I can't see properly and feel trapped in a mobile prison. But threatened? No! LIZ JONES [journalist] describes her week in a BURKA."

BJ's article was published 5th Aug (2 incidents), 6th Aug (2 incidents), 7th August (3 incidents)...Liz Jones' article was published 11th Aug (7 incidents), 12th Aug (7 incidents), 13th Aug (6 incidents).
The final line of Tell MAMA's 100 page report (no, I haven't read it all!!) slightly undermines their claim that Boris Johnson's remarks were responsible for the 'significant' spike in August.The last paragraph deals with police incidents;
"The annual timeline for anti-Muslim incidents reported to our police partners in 2018 showed minor spikes in March and August and a significant spike around April and May" ... "These spring-time spikes match those recorded by Tell MAMA" ... "There was a slight increase in August, rising by 10% since July, which we tend to see during the summer period."
They didn't refer to Boris Johnson's August comments here.
