The Bible paints a clear picture of tolerance in these instances.
Him that is weak in the faith receive ye, but not to doubtful disputations. For one believeth that he may eat all things: another, who is weak, eateth herbs. Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
Romans 14:1-3 (KJV)
One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.

Romans 14:5 (KJV)
Although the Bible clearly condemns the eating of pork and other types of meat in the Old Testament, it seems to justify the eating of pork in the New Testament.
Leviticus 11:7-8 (KJV)
Acts 10:10-16 (KJV)
There are a couple of interesting things to note about this passage. The first is that according to the context, this is an object lesson designed to teach Peter that he was not to avoid contact with the Gentiles. The second thing to notice is that there is no implication that Peter actually ate any of the food.
On the celebrating of holidays, the Jews were clearly commanded to celebrate and recognize specific holidays. In the New Testament Christians are neither commanded nor forbidden to celebrate holidays. Although many, if not most, of our holidays (Christmas, Easter, etc.) have pagan origins, the Bible is silent on forbidding us to celebrate them.
Even meat sacrificed to false gods is not forbidden.
Whatsoever is sold in the shambles, that eat, asking no question for conscience sake: For the earth is the Lord's, and the fulness thereof. If any of them that believe not bid you to a feast, and ye be disposed to go; whatsoever is set before you, eat, asking no question for conscience sake.
1 Corinthians 10:25-27 (KJV)
The word shambles here refers to a meat market. The clear indication is that whether you buy the meat yourself and take it home to cook it, or you are invited to another's home to eat, you as a Christian are under no obligation to refrain from eating it.

Again it says in Romans:
He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks. For none of us liveth to himself, and no man dieth to himself.
Romans 14:6-7 (KJV)
We are each serving God to the best of our ability. Your fellow Christians may not do everything exactly like you do, but that doesn't mean they are wrong. We should not condemn them; they should not condemn us. There are instances, though, where we should refrain from certain things (eating certain foods or celebrating certain holidays) if it is offensive to our brethren.
Romans 14:13-17
We are not to even put a stumbling block before the lost:
If any of them that believe not bid you to a feast, and ye be disposed to go; whatsoever is set before you, eat, asking no question for conscience sake.But if any man say unto you, this is offered in sacrifice unto idols, eat not for his sake that shewed it, and for conscience sake: for the earth is the Lord's, and the fulness thereof:
1 Corinthians 10:27-28 (KJV)
In these instances we should be tolerant of our brethren who don't believe exactly as we do in these areas. If you want to eat meat; eat meat. If you want to celebrate Christmas, Easter, etc.; celebrate them. If you don't want to do these things then don't. The key is we should all respect each others personal beliefs.
Tolerance, however doesn't extend in all directions unrestrained. There is clear indication in the Bible that sin (anything that runs counter to the righteousness laid forth in the Bible) should be condemned and rebuked.
Ephesians 5:11-12 (KJV)
Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.
Galatians 6:1 (KJV)
