Concern in this context is that most Brits I know have taken no interest in understanding why things are the way they are. They don't seem to care at all, they don't even see any issues outside of those fed to them by the state media.
When their only source of information is the state media, they will always be disinformed by those who have corrupted these nations.
To them, the solution is to vote for the other party next time. Maybe that will change here now that there seems to be a genuine opponent to the state and it's getting people fired up in a good way. As long as it doesn't turn into another Trump, which is entirely possibel. Very few, if any, governments deserve any kind of praise in this day and age.
