Yes. Mistreating people who disagree with you is intolerance. Just because you defend minority rights doesn't mean you can't be intolerant.
You can but you have to make substitutions. Here are some alternative cakes and ways to make it safer for those with lactose intolerance: http://dairyfreecooking.about.com/od/occasionscollections/tp/BirthdayCakes.htm
Acknowledging one's hypocrisy is the first step towards self-awareness and growth. By admitting to being a hypocrite, you are taking responsibility for your actions and showing a willingness to change those behaviors. It's not about whether you are "really" a hypocrite, but rather about how you choose to address and amend your behavior moving forward.
it takes all sorts to make a world
You are probably lactose intolerant
If you're lactose intolerant, sure.
Yes, as could any diet that is vastly different from one your body is used to. Our systems can be quiet delicate to change, but should adapt rather quickly. If your symptoms do not improve within two weeks, or get worse, you probably have some lactose intolerance. You may not have noticed said intolerance before, even when you ate cheese, but the increase amount of cheese and the reduction of bread yeasts in this diet can make those slightly intolerant become more intolerant. Try over-the-counter remedies for lactose intolerance. In addition, following the diet plan as instructed (move on to the phase where you add in healthy grains and veggies) will have you eating more normally. DO NOT stay stuck in phase one just because you think you'll loose weight faster that way--it is unhealthy.
Lactose intolerance results from an inability in the small entrails to digest lactose. You can get so many carbohydrates or sugar in milk what's called lactose. You should avoid this.
Some people need to avoid dairy produce but others do not. Many people have a food intolerance often without being aware of it. If you do have an intolerance or masked/hidden/addictive allergy to dairy produce, consuming it can make it much harder for you to lose weight. .
It would depend on your definition of hypocrite. Churches are full of hypocrisy but people on the outside look at someone who believes that they are saved by grace, but still makes mistakes is a hypocrite. If I tell you that something is a sin, yet am willfully committing that same sin, that would make me a hypocrite, but the Word of God would still be true. Maybe it is that you don't spend time in the Bible, but the best way to answer someone that you think is a hypocrite is to have some biblical experience yourself, so may I suggest that you read James Chapter 3. This I assure you will help. Maybe suggest it to your friend as well.
If it was left out at room temperature, yes it could make you sick.
No. And if the person with asthma is lactose intolerant, milk may make it worse.
Ice cream manufactuers are always looking for ways to improve their product which does mean they can sometimes change their recipe to make it cheaper to make, better quality etc. Ice creams contain milk and/or cream therefore if you are lactose intolerant then you should go and see your GP. The GP can do a simple test where you drink a cup of lactose solution (tastes fairly sweet as it is milk sugar) then every 10 mins your lactose levels are tested with a machine. If your lactose levels remains quite stable for the test then it shows that your body is not breaking down lactose and that you are lactose intolerant. Being lactose intolerant is not the end of the world as there is many diffrent products that have been and are being developed for people with intoleratants to some foods.
