There is plenty of meat and animal products in supermarkets that doesn't come from the UK too. And even though there are strict rules here, there have been cases where people in these industries have been caught being cruel also.
If you eat or use animal products you are contributing to animal cruelty, there is no getting away from it.
Complaining about one side, that you won't ever use anyway, while utilising the other on a weekly basis, because that one benefits you, is hypocrytical, 100%.
The alternative is to be consistant in your beliefs before lecturing others, if you're not it totally undermines everything you're saying.
I would never, for example, campaign for marriage equality, then tell my kids its wrong to be gay, or stand outside an abortion clinic telling the people its a sin and make them feel shitty, then go and have an abortion because it suited my needs, or protest against domestic violence, then stick up for a family member who was hitting his wife. I would also never say that the modern fur industry is completely wrong and immoral while also eating meat, wearing leather shoes and benefiting from cheap milk, eggs etc.
You cannot lecture people and complain about something you also contribute to.
