So what always happens in these discussions is that xenophobes realise that 14,000 asylum seekers a year doesn't actually sound like that much, in a country of 67 million people, and so they try to conflate it with overall immigration, which sounds a lot scarier.
But this also just showcases their ignorance. For example a third of overall immigration is for study purposes. These are people coming temporarily to the UK, injecting billions of pounds into our universities and economy, and without access to benefits. They are typically young, healthy with no dependents. They pay much higher tuition fees and subsidise home students -- many university programmes would not exist without foreign students.
This is all a good thing! As are the many doctors, nurses, engineers, butchers, agricultural workers who come here on work visas.
But this will never be acknowledged. They are just portrayed as a faceless wave of non-white people coming here to destroy British values and implement sharia. And I mean literally portrayed, as during the Brexit campaign.
So again, there is no point trying to reason with these people. You are not going to change their mind. I know it's really hard not to argue! But we are just wasting our time.
