By the time philosophy percolates down to the common man, it passes through many filters of ever greater simplification to the point it is almost unrecognisable as philosophy, and becomes a part of the always-already conditions into which we are born. One can say much the same for religion or science.
At least in the West, both in form and content, and not without struggle and "two steps backward," what has emerged as part of the natural world-view seems far from dangerous. The belief that reason is important in finding solutions and answers to important questions, and that every rational person is therefore able (at least in theory) to do so, and that to do this persons must be free from constraints is one of the legacies of the philosophical tradition.
Over centuries, this theme has undergone practical changes as society extended rationality to include more and more groups of people, from non-landowners to slaves to women, and it was later philosophy that helped bring about this change to the fundamental world view (one has only to think of the evolution of the doctrines set forth in the Declaration of Independence and the Constitution) that now seems destined to extend beyond the dynamic West to the static East.
The same theme contributed to the rise of modern science and to a gradual freeing of mankind from superstition and reliance on dogma when it became allied to the other philosophical themes of skepticism and analysis first announced by Socrates.
If there are dangers, and I think there are, it is TO this thematic tradition FROM other areas of human activity that repudiate it.
