"FPTP is great for creating strong governments which can take action."
While this is true, the problem is that it artificially inflates the support for those governments, so that the action taken is rarely (in fact, since our modern voting system was finalised in the 1950s, never) in this wishes of the majority of voters (here I am ignoring the deflated turnout). The 1997 landslide for Labour was a particularly awful example of this -- ditto 2015, if it comes to that, when the Conservative party obtained a (slender) majority despite essentially matching their 2010 support levels.
I can recite the arguments in full but I already know OG that you aren't a very receptive audience. For now, let me just point out that of your three advantages of FPTP, the first is (as I said) massively misleading anyway, because: first-choice support is often affected by tactical voting (I chose Labour in 2015 not because I supported that party but because I didn't want the SNP to win); the existence of de facto "safe" seats allows a party to impose candidates anyway -- while the inverse problem is that most campaigning is focused on key marginal constituencies at the expense of the rest of the country; and compromise candidates aren't necessarily a bad thing anyway. Being strongly appealing to a minority, or acceptable to a majority. What is so awful about the latter?
The flaws of FPTP are evident and, mostly, avoidable. And you don't even have to switch to full-on PR either. At any rate, reporting criticism of FPTP as nonsense is frankly far more nonsensical. There is no dispute that FPTP is awful in many ways. If you don't mind those flaws, fair enough, but to pretend that they don't exist is massively dishonest.
