I think it would be likely. Britain is a country that is well-developed and has a decent military. If you are referring to war in London or other big cities, I think the armies would try to keep warfare on the battlefield, not urban areas. However, to counter that, (correct me if I'm wrong), I believe London is on the water, so a type of naval invasion would be likely. It also depends on who the fighters are. Britain v. U.S.A. for example, evacuations of cities would begin, and it's likely we'd see another Refugee Crisis like the one happening now in Europe, but smaller. But the U.K is part of the U.N., a huge group of unified countries. If war were to break out, it's likely forces would be pushed out easily with the help of other powers/countries.
Some (not all) men are against shifting gender roles because, historically and presently the nature of gender roles typically put males at a societal advantage. So the concept of having shifts in these gender roles, means that many males are often nervous that they will lose the stability in the systematic designation of societal standing due to gender, that was always designed to favour them. Although these fears are irrational, as most of the modern movements in relation to gender roles are in favour of freedom of the individual, and not intended to put any group or person at a disadvantage.
