Good man Vishnu! You are a worthy opponent and a good sport. Apparently the same cannot be said of your titled opponent in that game. 

Flagging is part of the game and is not unethical. Just because it doesn't apply to over-the-board games, doesn't mean it's unethical when in an online context. If anyone objects to flagging, there is a simple way to avoid it online, and that is to add a 1-second increment to any blitz or bullet (or even longer) games. That way, you can always premove and gain seconds back and not be flagged when in time-trouble. If you don't like flagging, then refuse to play fast games without a small increment. It is as simple as that.

To both agree to a fast game with no increment, and then insult your opponent for taking full advantage of such games by flagging, is poor sportsmanship. This fellow was a sore loser and was bullying you. Most chess players are kind (much more than in other games), but some of them, even titled players, can be rude on occasion. That this player has an official FIDE title, as well as that he's playing a weaker untitled player as well as a very young player, make this even worse and more offensive.

You're going to find players sometimes are rude, both online and over-the-board, and so this is a good opportunity to use it as a learning experience to not "go on tilt" and be distracted by such a reaction. Sooner or later, in an OTB tournament, after a game, your opponent will be a poor sport and make an insulting comment. It's good to have developed the skill to be able to not be bothered and know that sometimes that happens and it's not about you, so that you may concentrate fully on the next round and not be distracted by it.

When I was 13 years old, I played in a simul with the top-rated player in the USA at the time, and he said something rude to me. As an adult now, much older than he was at the time, it would mean nothing. But at 13, to be insulted by a titled player meant a lot, and I remembered that very unpleasant moment for years, I was losing and wanted to play all the way to mate, and I made an illegal move with my king, a couple of moves from mate. I pointed this out, and he glared at me, sighed, and said, "does it really matter?" Well, it did to me, as while in a normal game I'd resign, I wanted to play to mate to have the game to show others, and I didn't want to have an illegal move nor to resign. But I suppose he expected me to resign. Looking back, that was a really rude thing to do to a 13-year-old who had traveled quite a way to get an opportunity to play in the simul with him. So titled players can be fussy, rude, and judgmental. You just have to accept that some of them are like that sometimes. I think you did the right thing by asking others about his complaint, in this case. And again, flagging iss part of the rules if you play online with no increment. just as playing all the way to mate when you are losing is always your right as a player. 

Hope that was helpful!

On a fun note, the Botez sisters, of whom I'm a fan, have a clever "dirty flagging" emote for subscribers on their Twitch stream. That's a fun way to deal with the issue!

Karpov, who was often in time trouble, said once, that poor time managing was as faulty as misplacing pieces. You see the idea: why would one not be permitted to take advantage of the faults from his opponent in a game like chess ?

And an other question is: would be the position so good, for the one who has spent more time than  should, if he would have taken less time to think? If yes, why not play faster then, and if no, why complain?

Is the game above considered flagging?

no not really

Can you guys give me an example of dirty flagging? Maybe show a game of that happening.
