YES VERY DANGEROUS INDEED! Here are some of the most dangerous things that happened to me while in India.
Dangerous to your prejudice!
I have never been anywhere in the world quite like India in this regard. People are just simply accepted. There is a difference between acceptance and tolerance. Most places I have been in the world, people are tolerant of tourist, religions, differences and color of your skin. India is accepting. It is truly the most endearing thing about this country in my eyes.
The Indian people have assimilated for centuries of occupations that has helped to create this acceptance. From the Muslim invaders to the British most recently, this country has not lost her identity over thousands of years, yet assimilates parts of the occupiers seamlessly. This is admirable and says a lot about the Indian people.
When you go to India, you let go of your prejudices. You learn from the Indian people how to get along with others and accept, which is the enemy of prejudice.
Dangerous to your tastebuds!
The food is a balance between spicy and sweet that simply makes me happy. There is little better feeling than the curries that tickle my lips with almost a buzz after eating Indian Food. From the biryani to the curries, from pani puri (sp) to the Chole Bhature and Kati Rolls of Delhi. By no means am I a vegetarian, however this is the only country where I could eat veg and not care one bit.
The Indian food is dangerous to numbing your tastebuds to really really good food with more flavor complexities than you are accustomed to.
Dangerous to your World View!
I can not honestly say that before going to India, my worldview was complete. It still isn’t complete by any means, but I thought I had a pretty good grip on it. After going to India… It exploded and made me realize how ignorant I really was to the views of others in the world.
The Indian people see life differently than the rest of the world. Not in a negative way, just very different. Maybe it is from being an ancient civilization and developing a philosophy that is tried and true. Coming from America, we have a civilization and culture of only a couple hundred years old. This is an infant to the Indians who have been entrenched in their culture since human existence practically.

So Is It Dangerous?
Go to India! See for yourself! It is dangerous for many reasons. But is it dangerous to your personal safety, (which is what the original poster was probably getting at)?
NOT IN OUR EXPERIENCE!
We never felt as if our lives were in danger, or that we were in a dangerous situation. Does it have its dangers… of course. Just like anywhere else in the world. Whoever is reading this can say the same about their own land.
There are dangers everywhere and it is up to you to be smart and travel well by avoiding the dangers or being put into dangerous positions where others can take advantage of you.
