Fox hunting is fucking cruel, that's obvious.
Animal cruelty aside, fox hunting isn't that harmful to fox populations in the UK. In 2003, sources say that only 6.3% of all killed foxes a year are killed by fox hunting while most are killed by either getting run over or disease.
Allowing Fox hunting could also help farmers defend Lambs and chickens from foxes (it's common for a farmer to lose up to 20 lambs a year to them).
However, Fox hunting does cause a lot of collateral damage to the area it's done in, it's been reported that otters and badgers have been killed by foxing dogs after the fox has been ripped to pieces and fields and gardens can be ruined after 2 dozen dogs rip through them. Not to mention that private property is sometimes intruded upon and, as it turns out, Feral bloodthirsty dogs don't care who or what they have to bite through to get to the fox.
Foxes are pretty common in the UK right now, and i'm willing to bet that even if it passes, it'll be banned in a couple of years anyway.
Anyone who actually does fox hunting is a spineless cunt and should kill themselves, but it's not like we needed another reason to hate May or UK parliament anyway.
If anyone gives a shit, my own opinion is fox hunting should stay banned, but it does have its (very small) perks
