I thought this might offer encouragement to some. Went to my local Tesco today and was astounded to see around 10 customers not wearing masks. Some were couples. This is the most I have ever seen going maskless as usually it is just me or one or two others. I would urge those that do not want to wear masks, but wear them out of fear, to put the fear aside and take the mask off. They have no legal capacity for fining you for not wearing a mask, you merely state you are exempt and do not have any other conversation on the matter. A few points below in case you are challenged.
State you are exempt ( do not give any other detail)
If asked to leave a store you would have to leave (under trespass laws) but advise them you will contact their head office as this is unlawful under the Disabilities and Discrimination Act https://www.legislation.gov.uk/ukpga/1995/50/contents Stores are not allowed to harass people with disabilities. The Coronavirus Act 2020 states that masks do not have to be worn where 'extreme distress' would be caused. Use it to your advantage.
If police stop you for not wearing a mask state you are exempt. Do not engage in any conversation with the police other than you are exempt and you have committed no crime. Do not give them any details unless they can tell you what crime they suspect you of committing. Ask if you are free to go and stick to it. There is NO CRIME they cannot arrest you for not wearing a mask.
Do not buckle, they have no right to tell anyone to restrict their oxygen supply and they know it. The legislation is fear and ignorance based which means they are relying on your ignorance to enforce it
I hope more will follow suit. It is critical we peacefully protect our freedoms from tyrannical liars! If you know that this is evil and continue to comply with it, you are consenting to what they are doing.
