Tolerance is a very good quality. One should not judge his fellow too harshly. Judaism is very clear about how we treat our neighbor. We are supposed to unload the donkey of our enemy if it is overloaded. We are to care for our neighbors lost belongings. Most importantly we are commanded to never hate our neighbor in our heart, nor to bear a grudge. Tolerance is very important in order to be able to satisfy these commands, between man and his neighbor. Baseless hatred is the quality which caused our Holy Temple to be destroyed. I fully understand tolerance and hope that others can find it in themselves to be tolerant of others who are not on the same high level as themselves. A holy person works hard on making himself better, but must not make others feel inadequate because of their lower levels. A righteous and holy Jew will be able to make the less observant desire to learn how to attain the higher levels of character traits. I am studying the Jewish Mussar called "Mesilat Yesharim" which teaches these ideas and how to tune into the higher levels.
It is important to remember that we are talking about our 'neighbors' or fellow Jews. This also extends to righteous non-Jews, proselytes and converts. But we must not accept evil and we must stand up against it. We must not hate an individual because he has an attraction for the same sex, but we must teach him that all of our desires are capable of being harnessed for the better good of humanity, and for the will of Hashem. Just as a Shabbat desecrator is condemned, so is a homosexual.
We must look for the good in all of creation, and find the spark of holiness which it contains. It is possible for the Chassid to raise up the sparks of holiness and bring about the rectification of all of mankinds sins.
Tolerance is wonderful, Acceptance can be a path leading to sin.
What Muman is saying is correct, but this only applies to the refutation of baseless hatred against one's neighbours. This is an important issue, perhaps the most important issue.
What are we required to tolerate? And what are we required to condemn? To me, this is a complex issue which can be made simple through the analysis of one of the most important concepts in Judaism--the concept of havdalah (separation). Much of Judaism is based on this concept. Even the most cursory glance at a list of the 613 mitzvot reveals that havdalah is a central Jewish concept.
As in the Creation, G-d separated day from night, land from water, Heaven from Earth, so to are Jews commanded to separate wool from linen, good from evil, men from women, and most importantly, good from evil. We must tolerate that which is good and rebuke that which is evil. To tolerate that which is evil is a perversion of havdalah.
For that reason, Judaism is not supposed to be as tolerant as many would like to believe. Unlike Christianity, which holds that it is right to hate the sin but love the sinner, Judaism holds no such view. As Jews were chosen to be a light unto the nations, one of the ways Jews must cast that light is to make it clear that we will tolerate that which is good or at least benign, and reject that which is evil or malignant. We are all charged with this task.
