The First Amendment existed to protect POLITICAL speech — words, first and foremost. In origin it did not mean to protect “arts” such as dancing, nor would most Founders have ever agreed that it protected lewdness.
James Madison on the First Amendment and licentiousness of the press:
Is, then, the Federal Government, it will be asked, destitute of every authority for restraining the licentiousness of the press, and for shielding itself against the libellous attacks which may be made on those who administer it?
The Constitution alone can answer this question. If no such power be expressly delegated, and if it be not both necessary and proper to carry into execution an express power--above all, if it be expressly forbidden, by a declaratory amendment to the Constitution--the answer must be, that the Federal Government is destitute of all such authority.

Jan. 1800 Writings 6:385--401
