RESPONSE: This video is just a piece of junk issued by a feminist theologian who rips the Traditional Latin Mass whenever she attends. Based on those comments, she doesn't exclusively attend.
Also, what is wrong with dressing modestly? Many traditional parishes have dress codes to uphold the dignity of the Most Blessed Sacrament, Our Lord of Lords and King of Kings.
If you are a Catholic of the Latin Rite, you are bound to attend this Mass, the same Mass said by Jesus Christ, the same Mass said by Saints Peter and Paul, the same Mass said by the Early Church Fathers, the same Mass said by Pope St. Victor the Great, the same Mass said by St. Augustine, St. Pius the Great (I), St. Gregory the Great, Venerable Bede, St. Boniface, Thomas Aquinas, St. Dominic, St. Anslem, and St. Pius V, the Pope who canonized the Mass on this day in the Year of Our Lord 1570 by issuing Quo Primum Tempore and De Defectibus.
