During the BLM/Antifa riots you had violent Far Left thugs attacking police, killing innocent people and police officers, burning down buildings and causing tens of billions of dollars in damages nationwide, mostly in deep blue Big Cities. This occurred over a period of many months.
On January 6 you had a small number of agitators take advantage of a peaceful political rally to trespass and damage some property in one government building over a period of about three hours.
Which is the above two incidents is far worse, any rational person can easily answer.
