gosh you must really hate your country (assuming your British, given you've policed the RF threads so intensely over the years).
what would you replace democracy with after you've 'dismantled' it? a religious state? anarcho-sydicalism? Is that you Vladimir?
if the name is any indication, perhaps something more in the French style, although they are a democracy too and you don't want that. Plus they've just jailed their former president for corruption, and don't seem to be doing so well with their minorities either (unless you'd be OK with a teacher beheading in Batley this week?)
After Brexit, sure lets plunge the place into decades of constitutional upheaval and crisis, where nothing else gets done while the various sides battle it out as to how the country should be 'dismantled' and what political philosophy should replace it, at a waste cost to the taxpayer that makes Brexit look like a child's pocket money.
Fewer than 100 hereditary peers remain in the HoL, most lords have previously worked in the public sector in various ways, minorities are in the minority because why would a minority in the population have anything other than a political minority too? Anyone can stand for election in this country, its very democratic, why would you want to 'dismantle' that? the RF will slim down with Charles, he's a reformer and has been saying this foe a long time. Its by no means perfect but no country is.
dismantle democracy. good idea.
