It seems they are in top 3 most popular rock bands in Britain and the British public is much less polarized on Queen than e.g. American. How that band have such a big appeal on Brits, bigger than on any other rock public worldwide? Is it a matter of British taste? 

Indeed. Their most popular/later work is what got exposed to the general public, whereas the earlier/more progressive material is mostly ignored by most.

I don't know, they were very popular in India too, not talking sales but just name recognition.  One of THE big 70s rock bands people tend to name along side LZ, Who, DP.  If I see the sales of albums like News of the World or The Game, they actually performed better in USA than in the rest of the world (including UK).  The Game was only Gold in UK but 4 x Platinum in USA.  It was the critics, led by Christgau, who seemed to thoroughly dislike Queen and/or view them with mostly unwarranted suspicion.  They had similar views on ABBA who have some similarities to Queen (I know Queen fans will never forgive me for saying this) and who also sold well in USA just like everywhere else.  The American band Sparks (whom I would argue both the aforesaid bands owe a huge debt to) found reception to their music in their homeland so hostile that they moved to UK and subsequently enjoyed their biggest success which of course was pretty modest compared to Queen or ABBA and understandably so.

pls come to Brasil!!!!

Seriously, not only SA featured one of Queen's hugest tour - which implies one of world's hugest tour - but to this day they are revered, especially Freddie Mercury, as amazingly lovable musicians. Anyone who doesn't like Queen and is over 40, in Brazil, has undeniably been in a coma in the 80s. Medical statement. 

I've tried but their inherent quirkyness pretty much means I'm not going to like much more that what gets played on the radio, along with a few other select songs. I admire their approach to making music. I love that they don't fit into the typical rock band mold of the time but much of their work just doesn't resonate with me.

Right, anyone can write a song like Killer Queen and Somebody to Love, and anyone can play the guitar like Brian May and sing like Freddie Mercury. I mean, I don't know about you, but I try my best *not* to write Billboard top ten songs and make albums that connect with tens of millions of people. It would be an absolute nightmare if, in throwing a tour, I kept selling out massive stadiums everywhere I went, all over the world. Imagine how horrible it would be to write a song like "We Will Rock You" and "We Are the Champions" in 1977, and 40 years later people still sing it at sporting events, knowing every line of the songs. Or even worse, writing "Another One Bites the Dust," which ends up being a key sample in the burgeoning genre of hip-hop, endlessly sampled 40 years later.
