There is no need for someone specific to do this such as a High Priest. There is need for people to stop worrying. You are not doing anything bizarre by browsing these forums, even if the enemy project this.
I can actually make some tutorials for these things in the closeby future. Even Windows 10 can be a 'relatively safe' operating system if you do the specific tweaks. However I found hardly anything about what you can do online. Therefore it may need a tutorial. There is a series of things you must do.
There are many good VPN services you can use. Just make sure they are a no-logs VPN. No logs means the company doesn't hold a file on what you do online (at least they claim so) and therefore anything you do online is private (again this doesn't apply to very serious offenses). You should be fine for example to access sites of political dissidents and other activities. Generally, VPN's are helpful, they can reduce internet speed, but they can of course up your online protection. You can also use pages such as this:

From here you can access sites without you being directly exposed to anything to the websites and/or the trackers in the sites. You can even see the forums and so forth.
If you want a safer search enginge, try this one - DuckDuckGo:

One last thing, these steps can protect you from data mining and other issues such as nutcase enemies who may snoop for your IP address, unless they are exceptionally skilled hackers which would be very time consuming to just pull on random members. Still, there is not many things they can do with this, but just to be sure, you can use this.
To browse the internet, Firefox seems to be the same. I wouldn't use google chrome, as it's used by google and it definitely data mines. Ice Dragon (based on Firefox) is also a good alternative that is relatively safe. You can combine it with the above and you can be quite sure that the greasy enemies who may try to scout on you and/or harass you will have a harder time.
Make it also a habit, especially on safe computers, to clean your internet history and so forth. Then you should be fine from most people who are snoopy and greasy and want data or to scout on you for absolutely no reason whatsover.
